Health and SafetyMilliken plug valves contain sealingcompound and grease which, for theirintended use, do not present asignificant hazard to health.

If skin contact occurs when rechargingthe valve with compound wash handsthoroughly with soap and water andmaintain good standards of hygiene.

Health and safety data sheets areavailable for each compound and giveguidance on safe handling and remedialaction if misused.

FlangesThis catalogue provides informationfor screwed end valves and valvesfitted with flanges to BS EN 1092-2and ANSI B16.1.Valves with BS10flanges can be supplied, details onapplication.

GearingIn this catalogue the dimensional tablesindicate where, in our opinion, valvesshould be fitted with gearing.

The principle of the Milliken plug valveis as simple as its design.The plug,which is the only moving part of thevalve, when open, presents a straightthrough passage in line with thepipeline, and when turned through 90degrees to the closed position stopsthe flow.

A special sealing compound is used toeffect a completely leak tight seal.When line pressure is applied to thevalve in the closed position, the parallelplug is forced to the downstream sideof the valve.The plug is then in contactwith the body in the area surroundingthe outlet port.The sealing compoundwhich surrounds the outlet port bymeans of special grooves in the plug,forms a barrier to line pressure. It isalso spread over the sealing surfaces ofthe plug and body so that a very thinfilm of compound is establishedbetween the plug and body surfaces onthe downstream side.

The metal to metal contact of plug andbody together with the barrier ofsealing compound ensures acompletely leak tight valve.The sealingcompound, to some extent preservesthe body and plug surfaces fromcorrosion, and provides lubrication forease of operation. Providing the valveis correctly maintained which ingeneral simply means injecting a smallamount of sealing compound fromtime to time and moving the plug, avalve giving positive shut-off will resultand provide many years of satisfactoryservice.

Valve Pressure / Temperature RatingThe pressure/temperature ratingsgiven apply to the valve only.Themaximum temperature at which avalve may operate depends upon thesealing compound with which the valveis filled. However, should the sealingcompound have an operatingtemperature different to that of the valve the lower temperature must apply.

Injection of CompoundWhen the combination screw hasreached its limit (screwed fully down)this indicates that the valve needsrecharging with sealing compound.

When using the lightweight compoundgun, remove the combination screw,partially fill the compound reservoir inthe plug, replace the combination screw,and screw down.

This operation may need repeatingseveral times.When using the NMG 40high pressure gun, attach the nozzle tothe injection nipple and give severalsteady stokes of the lever.

VALVES MUST EITHER BE FULLY OPENOR FULLY CLOSED WHILST THEY AREBEING CHARGED.

Indication of Full ChargingThe first indication of the valve becomingfully charged is an increase in the effortrequired to rotate the combinationscrew, or with the high pressure guninjection an increase in the effortrequired on the lever.

The effort required to operate the valveshould have increased from the initialoperation prior to injection of sealingcompound.

Method of injectionWhere the number of valves to becharged is small, i.e. 12-15 valves,especially if they are in the smaller sizes,lightweight gun injection can besuccessfully used. For larger quantitiesuse of the NMG40 high pressure gun isrecommended.

Valve LeakageLeakage through the valve indicates thatthe valve requires injection of sealingcompound or that it needs opening andclosing a minimum of three times todistribute the compound evenly.

Operating TorqueShould a valve become jammed orunusually stiff to operate, this can begenerally cured by the injection of sealingcompound. If this is ineffective, it will benecessary to dismantle the valve, cleanthe components and recharge withsealing compound.

SealingIn service sealing compound should beused for each individual medium to affectgood isolation. Our recommendations forsealing compounds are the result ofconsiderable research. If there is anydoubt as to the suitability of a particularcompound for a given service, test shouldbe carried out in a new clean valve.This isthe only way to conduct such tests.Laboratory tests using a beaker of linefluid and immersing a stick of compoundhave proved misleading.Where samples offluid can be supplied, together with detailsof temperature and pressure, and ifknown frequency of operation, we willcarry out specific tests and give ourrecommendations based upon the results.

ConstructionOnly five major parts are involved whendismantling i.e. body, parallel plug, PTFEthrust ring, bottom cover and plugsupport spring.

OperationCare must be taken particularly withgeared valves that the plug is eased offthe body stop after operation to ensurethe plug is free to float.

Routine MaintenanceValves are despatched by Hattersleycharged with sealing compound.Acompound identification tag states clearlythat the valve has been assembled andtested with a universal compound.Theuser is advised to follow the chartoverleaf for specific applications.Wheninjecting additional sealing compound, careshould be taken to ensure that it is of thecorrect type.Where the service permits,the valve should be partially or fullyoperated once to ensure free operationand to determine the effort required.

For infrequently operated valvesmaintenance merely consists of two orthree turns of the combination screw or,if gun injection, several strokes of thelever, and opening and closing the valve aminimum of three times to distribute thecompound evenly around the plug atthree monthly intervals. It is difficult to bespecific how often the valve should berecharged with sealing compound, sincethis is determined by the frequency ofoperation, type of service, pressure andtemperature.
