Ball valves

  • WCB Carbon Steel Valve Body: The valve body is cast of ASTM A216 WCB carbon steel, featuring high strength, good weldability and cost-effectiveness. It is suitable for normal temperature service and non-strongly corrosive medium working conditions.

  • Floating Ball Design: The ball floats freely under medium pressure and closely fits the downstream seat to form a tight seal. It features simple structure, reliable sealing and moderate operating torque.

  • 2-Piece Design: The valve body is split into left and right sections. The middle cavity allows easy maintenance and inspection, reducing downtime and lowering the whole life cycle cost.

  • Flange Connection: Adopts RF (Raised Face) flange connection in accordance with ASME B16.5 standard. The 6″ 300LB size matches standard pipeline dimensions with excellent installation interchangeability.

  • API 6D Certified Construction: Compliant with API 6D pipeline valve standard. Optional Double Block and Bleed (DBB) function meets the requirements for cavity inspection and maintenance of pipeline valves.

  • Full Bore or Regular Bore: Optional Full Bore design allows pig passage; Regular Bore reduces cost to meet differentiated application demands.

  • Fire Safe Design: Compliant with API 607 standard. Graphite packing and metal sealing pairs can still maintain tight sealing under fire conditions to prevent medium leakage.

  • Anti-Static Device: Conductive components are installed between stem, ball and valve body to effectively prevent static accumulation and reduce fire and explosion risks under flammable medium service.

  • Blowout-Proof Stem Design: A shoulder structure is designed at the bottom of the stem to prevent stem ejection under internal pressure, ensuring safety for operators and maintenance personnel.

  • Low Emission Packing System: Adopts combined V-type PTFE or flexible graphite packing, meeting ISO 15848 low emission requirements and reducing escape of volatile media.

  • ISO 5211 Top Flange: The actuator mounting flange complies with ISO 5211 standard, enabling direct installation of pneumatic, electric or gas-hydraulic actuators.

  • 2-3 piece body

  • Full andreduced bore trunnion mounted

  • Double block and bleed

  • Single or double piston effect design anti-blow out stem

  • Anti-static device

    J-VALVES SPE can supply a range ofseat types and configurationsto meet specific process needs:

    J-VALVES trunnion mounted ball valves standard seat ringsare soft-seated by the use of athermoplastic or elastomeric or Meta

    Seats-Tungsten /Chrome carbide /ENP

    6

    Single Piston (SPE) , Double Piston effect (DPE) and Combination (SPE x DPE) seats are available.

    7Seat Princlple

    Two independent seat rings grant the sealing, barrieragainst the line pressure actingon the upstream and downstreamsides of the valve which allows the valve tobe bidirectional.


    A set ofcoil springs acting, between the upstream side ofeach seatring,andthe body,generate an uniform thrust on theseat which push the same against the ball and grant the sealingfeature with no orverylow pressureinthe line,when the line pressure increasethe thrust actingon theseat increases proportionally and the sealing leatureis granted throughout the fullpressure range.


    The J-VALVES SPE trunnion mounted ball valves are available with Double

    Block & Bleed in dependent oftheseat type.

    Double BarrierNoYesYes (preferred direction only)

    8Single Piston Effect

    Single piston effect (SPE) is the stand ard feature for theseat rings of the J-VALVES SPE trunnion mounted ball valves.


    On a SPE seat ring:

    The pressure ac tingon the upstream side ofthe seat ringgenerates aforce which push theseattowards the ball.The pressure actingon the downstream side ofthe seatring generates a force which pull theseatring away fromthe ball.


    Anyoverpressure which may be generated by the thermal expansion of the fluid trapped in thebodycavity with the ballin fully closed position, will beautomatically dischargedinthe line on the lower pressure side.


    9Double Piston Effect

    Double piston effect(DPE) is a stand ard feature fortheseat rings ofthe J-VALVES trunnion mounted ball valves & recommended forwelded body valves. Ona DPE seat ring, both the pressure acting on the upstream sideof theseatring andthe pressure acting on thedownstreamside of the  seatring, generatea forcewhich push the seattowards the ball.


    With th is type ofseat ring,the eventual over press ure whichmay be generated by the thermal expansion ofthe fluidtrappedinthebodyeavitywith theball in fullyclosed position,can be discharged by the use of:

    An external safetyrelief device.

    The Double Piston Effect grants a double sealingfeature,iftheupstreamseat ringisdamaged, thedown stream seatgrant the sealingfeature of the valve.

    Stem

    • The stem is independent from the ballandis not subject to theside load generated by the line pressure acting on the ball. 

    • Two O-Rings and agraphite gasket grant a triple barrierand thefire safe sealing on the stem.

    • Abuilt instemsealant injectionsystemis provided as

      a standardfeature.

    • The standard antIblow-out eature ofthe stemis

      inaccrdance to API6D and is granted by the bodvcover. By removing the gland bushing the upper stem gasket can be replaced for

      maintenance with thevalve in service.

    11

    Ball

    • Inside entry valves 4" and smaller the ball is kept in position by an upper and alower trunnion,housed

      in the primary body.

    • Inside entry valves 6" and larger the ballis kept in position by an upper and alower trunnion, housed

      in two bearing blocks

    • Both the trunnions absorb the side load generated by the line pressureacting on the ball,without affecting the rotation of the stem

    • Large diameter trunnions minimize the torque required to operatethe valve.

    • The trunnion srotateinto metalbacked

      self-lubricating bearings.


    12

    Emergency Seat Injection

    • Emergency grease in jection fitting forseat rings are standard for6" and larger valves and as option on sizes 2"-4".

    • An eedle valve, complete with non return check valve is screwed in the bodyand connected to theseatrings.

    • The emergency sealantinjection can temporarily solve leakage problems, seatsshall be re paired at the first opportunity.

    • For valves smaller than 6" seat sealant in jection fitting can beprovided in the body cavity

    13

    Body Vent & Drain

    • All J-VALVES SPE TMBV are complete with ascrewed NPT Plug, located in thelower side of the body completedraining of the body cavity.

    • For valves up to size 4"the drain and vent are combined in oneport.

    14Double Block and Bleed

    This feature permits to check the integrity of the seats without interfering withthe operation ofthe line andthe replacement of the upper stem seal with the valve inline. The body cavity can be drained and depressurized with the ball infully closed position, this feature which is available with all typeof seats(SPE,DPE or Combination) permits.
