AIL Forged Steel Y-pat tern Globe and Check

Valves have established themselves in the industry

for their rugged and compact design, and reliable

service. These valves are of fered in Carbon Steel andAlloy Steel. They are available in a range of sizes

starting from 1/4” to 2” (in reduced-bore design) and

from 3/8” to 11/2” (in full-bore design).

The rugged construction ensures an ideal body and

bonnet, suited to handle high pressure andtemperatures - up to 4250C in carbon steel and 5400C

in alloy steel.

The Y-pattern design ensures a near-per fect straight

flow which significantly reduces pressure drop and

turbulence when compared to conventional designs.

As a standard, valves are supplied with screwed body-

bonnet joint, which ensures ease of inspection and

in-line maintenance, thus minimising downtime.

AIL Y-pattern valves can be of fered to NACE MR-0175 andother special NACE requirements. They can also be

supplied with IBR certification.

Familiarity with our catalogue numbering is not necessary when specifying or ordering our valves. A fulldescription of the valve provided by you is translated into a catalogue number as per the system shown.

For any other special requirement, add SPL to the catalogue number and provide details.

Y-pattern Globe/Check Valves

Y-pattern Globe ValvesDisc and SeatThe disc is provided with two integral rings to guide it throughoutits travel in the body. This minimises side thrust on the disc andeliminates bending of the stem even at high flow velocities. Bodyand disc seats are hard-faced to ensure a long, trouble-free lifecycle.

Disc-Stem ConnectionThe unique joint at the discand the stem provides for aflexible yet strong connectionthat enables the disc to freelyfloat on the stem. This resultsin perfect alignment of the discwith the stem.

Body-Bonnet JointThe bonnet is screwed to the body with ACME threads to ensureease of dismantling and resistance to galling. A graphite gasketis provided for tight sealing. This joint is tack-welded to preventloosening while in service. The bonnet can be easily removedfor inspection and maintenance of inner parts. The joint canalso be seal-welded on request.

PackingDie-moulded graphite rings are used as packing to provide foroptimal per formance at high pressures and temperatures. Twofilament rings provided at the top and bot tom of the graphitepacking rings act as anti-extrusion rings. Moreover, a smoothsurface finish on the stuf fing box along with a precision-machinedstem ensure optimum sealing and packing life.

StemThe stem is ACME-threaded and is ground for smooth operation.

Gland ArrangementThe two-piece ball-type gland flange arrangementensures uniform loading on the packing even incase the gland is unevenly tightened.

InstallationGlobe valves can be installed, either with the flowover or under the disc, depending on the servicecondition. However, in the case of steam and othersuch hot services that include drain lines, globevalves ought to be installed with flow over the discto aver t unseating caused as an ef fect ofdif ferential thermal expansion that would otherwiseresult in leakage and consequent wire drawing.

End ConnectionSocket-weld ends to ASME B16.11But t-weld ends to BS 5352 Annexure DScrewed ends (NPT) to ASME B1.20.1

Bore DiameterBoth Class 1500 and Class 2500 valves have borediameters conforming to Class 1500-StandardBore of BS 5352, with the exception of 15mm Class2500 valve which has a bore diameter of 14.5mm.

Y-pattern Check ValvesY-pat tern Check Valves incorporate the samedesign and construction features as their globevalve counterpar ts. The spring-loaded discminimises chat tering and enables the valve to beinstalled either in a horizontal or vertical position.

AIL Forged Steel Y-pat tern Globe and Check

Valves have established themselves in the industry

for their rugged and compact design, and reliable

service. These valves are of fered in Carbon Steel andAlloy Steel. They are available in a range of sizes

starting from 1/4” to 2” (in reduced-bore design) and

from 3/8” to 11/2” (in full-bore design).

The rugged construction ensures an ideal body and

bonnet, suited to handle high pressure andtemperatures - up to 4250C in carbon steel and 5400C

in alloy steel.

The Y-pattern design ensures a near-per fect straight

flow which significantly reduces pressure drop and

turbulence when compared to conventional designs.

As a standard, valves are supplied with screwed body-

bonnet joint, which ensures ease of inspection and

in-line maintenance, thus minimising downtime.

AIL Y-pattern valves can be of fered to NACE MR-0175 andother special NACE requirements. They can also be

supplied with IBR certification.

Familiarity with our catalogue numbering is not necessary when specifying or ordering our valves. A fulldescription of the valve provided by you is translated into a catalogue number as per the system shown.

For any other special requirement, add SPL to the catalogue number and provide details.

Y-pattern Globe/Check Valves

Y-pattern Globe ValvesDisc and SeatThe disc is provided with two integral rings to guide it throughoutits travel in the body. This minimises side thrust on the disc andeliminates bending of the stem even at high flow velocities. Bodyand disc seats are hard-faced to ensure a long, trouble-free lifecycle.

Disc-Stem ConnectionThe unique joint at the discand the stem provides for aflexible yet strong connectionthat enables the disc to freelyfloat on the stem. This resultsin perfect alignment of the discwith the stem.

Body-Bonnet JointThe bonnet is screwed to the body with ACME threads to ensureease of dismantling and resistance to galling. A graphite gasketis provided for tight sealing. This joint is tack-welded to preventloosening while in service. The bonnet can be easily removedfor inspection and maintenance of inner parts. The joint canalso be seal-welded on request.

PackingDie-moulded graphite rings are used as packing to provide foroptimal per formance at high pressures and temperatures. Twofilament rings provided at the top and bot tom of the graphitepacking rings act as anti-extrusion rings. Moreover, a smoothsurface finish on the stuf fing box along with a precision-machinedstem ensure optimum sealing and packing life.

StemThe stem is ACME-threaded and is ground for smooth operation.

Gland ArrangementThe two-piece ball-type gland flange arrangementensures uniform loading on the packing even incase the gland is unevenly tightened.

InstallationGlobe valves can be installed, either with the flowover or under the disc, depending on the servicecondition. However, in the case of steam and othersuch hot services that include drain lines, globevalves ought to be installed with flow over the discto aver t unseating caused as an ef fect ofdif ferential thermal expansion that would otherwiseresult in leakage and consequent wire drawing.

End ConnectionSocket-weld ends to ASME B16.11But t-weld ends to BS 5352 Annexure DScrewed ends (NPT) to ASME B1.20.1

Bore DiameterBoth Class 1500 and Class 2500 valves have borediameters conforming to Class 1500-StandardBore of BS 5352, with the exception of 15mm Class2500 valve which has a bore diameter of 14.5mm.

Y-pattern Check ValvesY-pat tern Check Valves incorporate the samedesign and construction features as their globevalve counterpar ts. The spring-loaded discminimises chat tering and enables the valve to beinstalled either in a horizontal or vertical position.

4 ASME B16.34 AIL Gate, Y-Globe & Check ValvesPressure Seal Bonnet design

The ASME B16.34 family of AIL Gate, Y-Globe and Swing Check

Valves features a pressure seal bonnet design for high pressure

services. These valves are extensively used in high pressure and

high temperature steam, oil, gas, chemical and water applications

in thermal power plants, fertiliser plants, petrochemical plants and

refineries. The valves are available with butt-weld ends in pressure

ratings of Classes 900, 1500 and 2500, and come in carbon steel

and alloy steel construction.

Gate valves also meet the requirements of API 600 Style A.

Seat Rings

Body seat rings are welded to the body to offer aleakproof design as they eliminate the leakagepath betwen the seat ring and the body. This designis superior to screwed seats which can loosen updue to temperature fluctuations, corrosion orvibration and result in leakage.

Trim

Both the disc and the seat ring faces are hard-facedwith Stellite #6 or equivalent.

Back-seat

The back-seat is in-situ hard-faced with Stellite#6 or equivalent.

Stem and Gland Packing

The valves feature a stem, made of 13% Cr. Steel -ACME threaded, precision-machined and ground to ahigh finish to ensure a smooth operation. The high-purity graphite gland packings, used for stem sealing,provide capability to withstand high temperatures andpressures, and also to resist many chemicals. Thesmooth-finish stuffing box ensures longer life for thepackings.

Accessories

AIL Valves can be supplied with accessories suchas bypass arrangement, drain plugs, live-loadingand mountings like extension spindles, floor standsand chain wheel. The valves can also be suppliedwith gear units and electrical actuators.

Yoke Sleeve and Thrust Bearings

The yoke sleeve is made of nodular Niresist Iron,supported by a set ofbearings to reducefriction and theconsequent torquerequired to operate thevalves. NodularNiresist Iron alsowithstands hight e m p e r a t u r e s .Weather seals,provided in the yokesleeve, protect the bearing area against ingressof dirt and water.

GATE VALVES

Parallel Slide Disc Mechanism

This mechanism consists of two independent discsheld by a disc carrier. An alloy steel spring betweenthe discs provides the initial loading to keep thediscs pressed against the body seats. The disc facesare parallel to each other and seal on parallel seatrings in the body. Sealing takes place by utilizing theline pressure to provide tight seal on the downstreamseat. As the two discs are independent and parallel,opening / closing torques are significantly lower thancomparable wedge disc designs, thereby minimizingthe possibility of jamming at high temperatures orpressures.

When the valve is operated, the discs are allowed toslide and rotate over the body seats. This helps wipeout foreign particles from the seat faces.

Pressure Seal arrangement for body-bonnet joint

This pressure seal body-bonnet joint utilizes the linepressure to create a tight body-bonnet seal. Sealingis achieved by compressing a high-purity graphitegasket between the bonnet and the body retainerring. Preloaded fasteners provide an initial tight sealat low line pressures. At higher pressures, the linepressure pushes up the bonnet against the gasket,compressing it further and providing a much tighterseal.

SWING CHECK VALVES

AIL Swing Check Valves feature a pressure-seal body-cover jointand seal-welded seat rings. The seating surfaces are hard-facedwith Stellite #6 or equivalent.

Swing-type Disc

The disc is of swing-type design and is opened by linevelocity and the resultant pressure. When the flowstops, the disc is closed by gravity. Seating load andthe resultant tightness are dependent on the backpressure.

As the disc is internally hinged, there is no opening inthe body of the valve. This ensures high integrity.

Installation

AIL Swing Check Valves are used to prevent thereversal of flow in vertical, horizontal or inclinedpipelines. These valves are to be used only forupward or horizontal flow. Pulsating flows, asobtained at the outlet of a reciprocating pump,would cause disc chatter and hence ought to beavoided.

End Connection

AIL Valves with butt-weld ends comply with ANSIB16.25 Fig. 2a or 3a, as applicable. For ANSI pipes,pipe schedule ought to be specified. For non-ANSIpipes, OD (or ID) and wall thickness ought to befurnished for end preparation.

Y-GLOBE VALVES

By virtue of their Y-type configuration, AIL Y-Globe Valves have arelatively straight flow and a lower pressure drop compared toconventional globe valves. The valves are suitable for tight shutoffand throttling in high pressure and high temperature lines.

Some of the unique features of AIL Y-Globe Valves are :

l Pressure Seal Bonnet

l Low operating torque due to use of thrust bearings

l Non-rotating stem

l Integrally-stellited body seats

l Fully-guided disc with Stellite seating and guiding surface

l Impactor handwheel in sizes of 6” (150mm) and above

As a standard, AIL Valves are made in Carbon Steel to ASTM A216Gr. WCB. For valves in other materials and for accesories like gearoperation and electrical actuators, suffix suitable abbreviations tothe above ordering code such as :
