Product Information

Trunnion Ball Valves

Seat Sealing
Soft seats are standard. Seat inserts of synthetic material such as Nylon,PTFE, RTFE or Peek are containedwithin a metal seat ring. With no orvery low line pressure, sealing betweenthe seats and ball is achieved by seatsprings. With higher line pressure, theline pressure, in conjunction with thespring load, forces the upstream seatring against the ball, which results intighter sealing.0-ring seat insertdesign is available.

Self Reli eving Seat
This standard feature is designed to prevent excessive pressure buildupwithin the valve by automaticallyrelieving pressure when body cavitypressure exceeds the spring load onthe seatsDouble Piston Seat is also available asan option.

Sealant Inject Fitting
This feature is standard except in sizes 2"-4" for pressure classes 150,300and 500, In case of seat ring damage,sealant injection provides a fast,reliable way to restore tight sealing,This injection system can also be usedfor routine flushing of the seat ring areawhile in service.

Double Seals at all joints

All connecting parts employ a doublr sealing design incorporating a spiralwound 316ssigraphite gasket ando-ring to ensure positive sealing.Delta ring is used optionally for class1500-2500.

Stem Sealing&Sealant lnjection Fitting

Two o-rings and graphite packing are used for pressure classes 150through 600. One each of lipseal ando-ring plus graphite packing are usedfor pressure classes 900 through2500, In case of damage to the o-rirglipseal, sealant injection stops leakingand restores tight sealing

Seat Ring Sealing
All connecting parts employ a double sealing design incorporating a spiralwound 316ssigraphite gasket ando-ring to ensure positive sealing.Delta ring is used optionally for class1500-2500

Actuation
JMC® Trunnion ball valves are designed to easily install a variety of actuatots including pneumatic,hydraulic, electric actuators, electro-mechanical, electro-hydraulic, vane, Hand operated valves are normally etc supplied with a lever or gear operator High-performance hydraulic actuators, which have been specialty developed for JMC® trunnion ball valves, can be supplied directly from SAMJIN JMCFurther information can be received on request.

Double Block and Bleed

JMC® Trunnion ball valves provide a positive seal at both upstream and downstream independently, Since pressure on each side of the ball is blocked from the body cavity, a pressure releasing device can be used by an operator to check the integrity of the upstream anddownstream seats


Low Friction Stem/Trunnion Bea rings and Thrust WRshers

Heavy duty PTFE lined carbon or stainless steel bearing and thrust washers ensure durable and low torque operation.
