JMC®Trunnion ball valves are designed to easily install a variety of actuators including pneumatic, hydraulic, electric actuators, electromechanical, electro-hydraulic, vane, etc. Hand operated valves are normally supplied with a lever or gear operator High-performance hydraulic actuators, which have been specially developed for JMC®trunnion ball valves, can be supplied directly from SAMJIN JMC Further 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 and downstream seats.
Low Friction Stem/Trunnion Bearings and Thrust Washers
Heavy duty PTFE lined carbon or stainless steel bearing and thrust washers ensure durable and low torque operation
