There are many definitions as to what is and is notconsidered to be a severe service application, whichmakes applications difficult to identify for valvemanufacturers and customers alike. An applicationis therefore generally recognised as severe serviceeither through past experience of problemsassociated with similar applications or because thepressure drop which the valve is required to handledefines the need for a specialist ‘severe service’control valve as per the valve manufacturersrecommendations. Unfortunately, this second pointis highly dependent on the product range offeredby a particular manufacturer to the point where anapplication may be considered severe service byone manufacturer but not by another.

However, in an attempt to clarify what is and is nota true severe service application, Weir Valves &Controls found that most applications appear to fallinto one of two categories, which are as follows;

• applications where there is a high pressure drop across the valve (for example in excess of 150 bar)

or

• applications where there are likely to be problems, such as cavitation, high fluid velocitiesor noise (an example of this would be an application where there may be as little as 40 barpressure drop across the valve but where the outlet pressure is only slightly above the vapour pressure of the line fluid such that an ordinary valve would be highly likely to cause the onset ofcavitation).

What is a Severe Service Application?

Severe service applications are consideredproblematic because of typical problems which arefound with the control valves fitted in these services.The valves are more susceptible to problems withinthese severe environments because of the largeamount of potentially destructive energy whichmust be removed from the fluid flow as it passesthrough the valve. Typical problems include;

• high fluid velocities,

• excessive noise,

• cavitation,

• severe erosion,

• vibration,

• seat leakage,

• poor flow control and general valve stability.

Blakeborough HOW THE X-STREAM™ WORKS - ‘3D’ FLOW CONTROL

XS 3-0406

The advantages of 3D flow control and theX-Stream™ trim

The X-Stream™ trim is the first in a new andadvanced generation of control valve technology,designed to manage the most severe of processenvironments with continued safe and reliableoperation. The X-Stream™ trim owes its superiorperformance to an extensive research anddevelopment program, which has resulted in thebirth of a new design methodology known as ‘3DFlow Control’. This new technique has been used tospecify the X-Stream’s unique design and flow pathconfiguration to ensure that the valve providesoptimum performance in service.

Controlling a new dimension

Severe service applications are notorious for causingproblems in the control valves responsible forhandling these arduous conditions. Typicalproblems include poor flow stability, cavitation,erosion (often first seen in the form of seat leakage)and excessive noise and vibration, all of which canhave significant effects on the successfulperformance of the valve. However, although theseproblems appear varied, in most cases they can beattributed to a poor control of the fluid flow as itpasses through the valve, leading to high pressuregradients, high fluid velocities and damaging levelsof kinetic energy within the fluid flow.Consequently, a typical severe service control valvewill use a number of stages of letdown (eitherthrough a labyrinthine style flow path or through aconcentric sleeve type cage design) to reduce thepressure drop across each stage, resulting in areduction of both the fluid velocity and kineticenergy levels. Unfortunately, this simplistic one-dimensional approach to the problem does not takeinto account the three-dimensional formation of thefluid flow as it passes through the valve. Recentresearch has shown that this can be just asdamaging if left uncontrolled.

No sharp corners

The primary feature of the X-Stream™ trim is the valvecage, a disc stack cage configuration thatincorporates a series of flow paths in which arelocated an array of staggered cylinders, as shown infigure 1. By forcing the fluid through these tightlypacked cylinder arrays, the flow is passed through alabyrinthine tortuous path which is able to dissipatethe fluid energy efficiently with limited pressurerecovery between stages and without the unnaturalmovement of the flow around sharp angled corners,such as those found in other severe service trims onthe market. This type of unnatural movement hasbeen found to result in numerous problems due touncontrolled three-dimensional fluid formations withinthe flow, such as separation and areas of re-circulation– see ‘3D Flow Control’ Explained, page 8.

Controlling fluid formations

As well as providing a method by which the overalldesign of the valve trim can be improved to moreeffectively handle the fluid flow, 3D Flow Controlalso allows the effect of any three-dimensional fluidformations within the flow to be understood andcontrolled by providing additional and moreaccurate information which can then be easilyincorporated into the standard valve sizingprocedures.

With the addition of these 3D Flow Controlparameters in the standard control valve sizingmethodology, each X-Stream™ trim is designed tomaximise performance for each and every set ofprocess conditions supplied. With a pressure dropcapability of the equivalent to 50 stages of letdownthe X-Stream™ is capable of safely handling pressuredrops of up to 400 bar and, on liquid flows, outletpressures that are as little as 0.5 bar above thevapour pressure of the line fluid without the onsetof cavitation.

Application specific materials and customcharacteristics

The X-Stream™ is designed to be fitted as a trimoption in the Blakeborough BV500 and BV990range of globe and angle control valves that rangein size from 1” (25 mm) to 30” (750 mm). Like allof the valve trim options within this range ofcontrol valves, the trim can be designed to providea variety of dynamic control characteristics rangingfrom the standard linear, equal percentage andmodified equal percentage characteristics to avariety of custom designed characteristics capableof meeting specific customer needs.

Depending on the size of the valve the rangeabilitycan be as high as 100:1. In all cases, the trimprofiles are designed by advanced computer basedprograms which are able to optimise the resolutionof the valve’s dynamic performance to match thecapabilities of today’s highly sensitive control andvalve positioning systems. The X-Stream™ trim canbe supplied in a wide variety of materials to caterfor every type of process environment and specifiedas either a welded or separable disc stackarrangement.

XS 3-0406

In order for you to see the distinct benefits of theX-Stream™ trim and the methodology used to wehave incorporated this in-depth section whichdescribes the research behind the design.

How the X-Stream™ Works – ‘3D’ FlowControl

Bringing in the third dimensionThe X-Stream™ incorporates a uniquely designedcontinuous resistance flow passageway tobreakdown the total pressure drop into muchsmaller stages by passing the flow through atortuous array of tightly packed cylinders. Thisincreases the resistance to the flow provided bythe passageway and therefore the valve trim, thusreducing the fluid velocity. However, unlike othersevere service control valves on the market, the X-Stream™ is designed and sized using themethodology of ‘3D Flow Control’.

The X-Stream’s unique continuous resistance flowpassage arrangement is the result of a 5 yearresearch and development program and has beendesigned using modern computational andexperimental analysis equipment. These advancedtechniques enable detailed understanding of howthe complex, tortuous flow paths used in othersevere service trims were able to handle the highpressure drops across the trim. It became clearthat the fluid flow through the passageways in thevalve trim were subject to high levels of turbulenceand a number of complex three-dimensional fluidformations such as areas of re-circulating flow,vortices and jet formations. The presence of thesedisturbances was leading to a wide variation inboth the local static pressure and velocity profilesthrough the flow path – see below.

Unseen velocity increases of up to 50%missed using normal sizing calculations

Further investigation revealed that the cause ofthese three-dimensional formations was, in themain, due to the complex geometry of the valve.For example, sharp, right-angled turns were leadingto large areas of re-circulating flow in the outwardfacing corners. This not only created an area of lowstatic pressure which, on liquid flows, could lead tothe early onset of cavitation, but also reduced thehydrodynamic area of the flow path leading to veryhigh fluid velocities. These were exacerbated furtheras the areas of high fluid velocity were forced toseparate off the inward facing corners as shown infigure 2.10. It was found that this large variation inthe local fluid velocity level caused the maximumvelocity in the flow path to increase by up toapproximately 50% of that predicted by traditionalone-dimensional control valve sizing methods.

As a result of these findings, the X-Stream™ flowpassage has been designed to provide a much more‘curved’ flow path; following the natural movementof the fluid flow in order to reduce the presence ofthese detrimental three-dimensional fluidformations. The close proximity of the cylinders toeach other means that the energy is released fromthe fluid through safely contained interactions andcollisions with itself, rather than the internal walls ofthe passageway which can lead to excessive erosionif left uncontrolled and seriously reduce the lifetimeand performance of the trim. As well as reducingthe presence of unsteady three-dimensional fluidformations both the local static pressure and thefluid velocity are controlled more evenly throughthe flow passageway. This results in an overallreduction in the maximum fluid velocity of around30%, based on the test results conducted duringthe research programme – see figure 2.11.

CFD identifies cavitation potential wherestandard methodology fails

Its unique flow passage design also provides the X-Stream™ trim with its self-cleaning capabilities, byallowing small particles to pass through the flowwithout obstruction, preventing particle build-upwhich can eventually lead to the flow pathsbecoming blocked and inevitably valve failure. Thevalve trim is also designed so that it can be easilymaintained on site and, where possible, a separabledisc stack gives maximum flexibility. In addition toproviding a superior valve trim design, the X-Stream™ is able to go one step further by applyingthe methodology of ‘3D Flow Control’ to the sizingand selection of the valve.

Whilst the X-Stream™ has a significantly improvedflow path which is better able to control the fluidvelocity, static pressure and prevent the onset ofcavitation there are still three-dimensionalformations within the fluid flow which can effectthe performance of the valve.

Whilst these three-dimensional formations exist,accurate fluid velocities are almost impossible topredict using the oversimplified one-dimensionaltheory which forms the basis of most existingcontrol valve sizing methods. This also means thatrelating properties such as the local static pressurelevels, temperature and fluid density used topredict the presence of cavitation or high levels ofnoise will be subject to some degree of inaccuracy.Some manufacturers will claim that whilst this istrue, the level of this inaccuracy is so small that itdoes not warrant further complication of existingsizing methods. However, although this may beacceptable for simple control valves, such as thosefitted with single-stage trim devices like theBlakeborough multi-flow or contour trim. Forhighly complex severe service trims the researchconducted by WVC UK indicated that this is not asafe assumption.

The investigation used two prediction techniques todetermine the onset of cavitation within an X-Stream™ trim: the first using computational fluiddynamics (CFD) to predict the points at which thelocal static pressure fell below the minimum staticpressure – see figure 2.12 - and the second wasbased on the same principles used in existing one-dimensional sizing techniques. The results werethen compared with the cavitation damage on anactual valve trim under the same conditions. Underthe one-dimensional prediction technique anaverage level of static pressure was assumed which,when compared with the fluid vapour pressure,was found to be higher suggesting no cavitationwould occur. Using the three-dimensionaltechnique (CFD) suggested local areas of cavitationattached to the sides of the cylinders, comparingvery well with the actual damage seen on theprototype trim – see figure 2.13.

Whilst it is not practical to conduct a CFD analysison every severe service control valve in order for itto be correctly sized, this evidence highlights thesources of error within existing one-dimensionalcontrol valve sizing theory and the importance ofunderstanding how the individual geometricalaspects of the valve can affect performance: forexample, changing the diameter or spacing of theholes in the concentric sleeve trim.

Based on in-depth study of the of the X-Stream™trim, Weir Valves & Controls has created a newsizing method in accordance with current IEC andISA standard sizing practices, which takes intoaccount the geometrical aspects of the valve thatmay affect its performance. Using this information,the valve is then sized based on themaximum/minimum fluid flow conditions, such asmaximum velocity and minimum static pressure.

The X-Stream™ is just one of the products in theWeir Valves & Controls ‘Blakeborough’ range ofcontrol valves, a name synonymous with qualityfrom a UK based manufacturer with over 50 yearsexperience in providing the customer withtechnologically advanced solutions. In addition, theBlakeborough product range includes an extensivechoice of control valve and desuperheatingequipment with expert application knowledge inthe power, processing and oil and gas sectors.

XS 3-0406

Cascade (CS)

The Cascade valve trim is a further advancementover the standard Multi-flow valve cage. It is used incontrol applications where high noise levels orcavitation would be predicted, with a standard trimdesign. Noise, flow erosion and/or vibration canresult in a high pressure drop/ratio application ifattention to controlling the pressure drop is notconsidered. The cascade trim has been specificallydesigned to eliminate these problems at source bycontrolling the pressure drop through a number ofdiscrete stages of let-down. The Cascade cage ismanufactured to close tolerances and consists of aseries of sleeves. The number of sleeves (stages oflet-down) required depends upon the amount oftreatment necessary for the particular application.Each successive sleeve, has a number of radial holes,and a carefully calculated increase in flow area toensure correct apportionment of the pressure drop.Thus, the small radial jets pass through a tortuousflow path resulting in high frictional andimpingement losses. At the same time theimpingement of the jets onto the outer radiallydrilled sleeves control the shock wave formationwhich has a major influence on overall noisereduction in gas/vapour applications.

Variable Stage Cascade (VS)

Is available when multiple stages of pressureletdown are required at low valve openings. Thisdesign particularly suits applications where there isa high-pressure drop at low flows, and a reducedpressure drop at normal to maximum flow-rates.The design philosophy of the Cascade and Multi-Flow Trims designs is combined within this trim.

This design option is utilised on flashing liquid,multi-phase fluids, and on contaminated gas/vapourflows. The unit is designed to prevent erosive outletflow, from the valve seat, directly impinging ontothe pressure containing body walls.

It is manufactured from hardened or hard-facedmaterial to reduce erosion rates. The design breaksthe erosive fluid flow into small jets and directs thebulk of the flow towards the valve outlet.

Bonnet forms

Standard

For applications where the temperature of thecontrolled fluid is between -18˚C (0˚F) and 232˚C(450˚F). May be used with graphite packing up to315˚C (600˚F). Although modern packagings aresuitable for much higher temperatures it isrecommended that the normalising bonnet be fittedin cases where the temperatures exceed the abovevalues to accommodate lagging of the control valvebody.

Normalising

For protection of the gland packing at temperaturesabove 232˚C (450˚F) and below -18˚C (0˚F) downto -100˚C (-150˚F) The bonnet is designed with finswhich dissipate the heat from process fluid and helpprotect the packings and actuator assembly fromhigh temperatures. In addition the normalisingbonnet is longer than the standard plain bonnet sothat the valve can easily be lagged withoutinterference with the actuator.

Bellows Seal

A positive leakproof stem seal for cases where glandleakage cannot be permitted. The standard bellowsmaterial is 321 stainless steel, although many othermaterials are available on request. The designconsists of a welded flexible steel bellows which isclamped in an extended bonnet/bonnet hood. Thiseffectively cuts out any possible leakage path aroundthe plug stem and therefore prevents emissionsfrom the valve packings. Packings are fitted in thesevalves but only act as a backup to the bellows.

Cryogenic

Used for temperatures below -100˚C (-150˚F). Thebonnet designed with a long necked section whichdistances the packing away from the process fluid.The necked section is designed with a minimumwall section to minimise heat transfer. Cold boxextension/cryogenic bonnets are also available.

Packing

Packings are selected based on fluid temperatureand fluid type. The most common packing systemmaterials are PTFE for low temperature andgraphite for high temperature. For hydrocarbonsservice and where emission levels need to becontrolled there are two further types of packingsavailable. These incorporate specially selectedmaterials and live loading to both minimiseemissions and extend packing life allowing for cyclicoperation. These packings are referred to as LTEPand HTEP. Packings have been tested to proveemission levels of less than 500 parts per millionover 50,000 cycles and under thermal cyclingconditions.

Characteristics

Linear

This characteristic provides a flow rate which isdirectly proportional to the valve lift. Theproportional relationship produces a characteristicwith a constant slope, so that with constantpressure drop the valve gain will be the same at allflows. The linear valve plug is commonly specifiedfor liquid level control and for flow controlapplications requiring constant gain.

Equal Percentage

Equal increments of valve lift produce equalpercentage changes in the fluid flow. The change inflow rate is always proportional to the flow rate justbefore the change in plug position is made. Theequal percentage characteristic is generally used onpressure control applications, and on otherapplications where a large percentage of pressuredrop is normally absorbed by the system itself.Valves with this characteristic should also beconsidered where highly varying pressure dropconditions occur or high rangeability is required.

Quick Opening

This provides for maximum change in flow rate atlow valve lifts with a fairly linear relationship.Additional increases in valve lift give sharply reducedchanges in flow rate, when the valve plug nears thewide open position, the change in flow rateapproaches zero.

Intermediate

Other intermediate or special characteristics areavailable on request to meet specific controlrequirements.

Soft seat

Is specified on applications where it is desirable tohave a maximum closure on the control valve. Thesoft seat design consists of a resilient seal ringclamped into the plug by a face ring. When the softseal contacts the valve seat, a lip on the seat bitesinto the face of the seal and effectively preventsleakage through the seat. The soft seat design canbe specified in both balanced and un-balanceddesigns.

Seal Rings

On balanced design valves the valve plug isdesigned to incorporate a seal ring which preventsleakage around the periphery of the valve plug.Depending upon the desired leakage andtemperature through the valve a variety of seal ringsare specified.

Plug designs

Balanced

The balanced plug design is utilised to greatly reducefluid forces acting on the valve plug allowingeconomical actuation and stable control. Thecylindrical plug head is drilled with balancing portsto admit pressure above the plug head. The annularleakage flow between the valve plug and cage isminimised by a sealing ring retained within a pluggroove. The standard sealing rings are carbongraphite which give Class III leakage. Alternatively a‘U’ seal can be fitted to give either Class IV or Class Vleakage dependent on seating load applied by theactuator.

Solid (Unbalanced)

The design is used on relatively low-pressure dropand/or on-off applications. It generally requires theuse of much larger actuators than would be requiredon the balanced plug design and in all but smallvalve sizes is not suited to control applications.

Pilot Balanced Trim

The pilot balanced plug design incorporates twoplugs, the main larger diameter plug used for controland the smaller pilot situated inside the main plugsignificantly reduces fluid forces acting on the mainplug. This design produces a high integrity metaltemperature where a resilient seal would beunsuitable. Opening of the valve is by the pilot plug,which lifts from its seat prior to the main plug head.This produces a flow passage to equalise the pressureabove and below the valve plug, thereby significantlyreducing the fluid forces acting on the valve plug. inthe closed position the inlet pressure is admittedabove the plug to produce a high downward seatload and the only leakage path is across metal tometal seating.

Flash-cone

This plug design is specified on applications requiringa very high rangeability. At low openings the conicalplug nose fits inside a matching conical seat. Theplug nose has a number of circumferential grooves,which produce a staging of the pressure drop as theflow passes between the small annular passagebetween the plug and the valve seat. In addition tothe increased rangeability this trim also allows thevalve to handle higher-pressure drops at low valveopenings than can be adequately handled by astandard plug design.
