Trunnion Ball Valve Seat Injection: Emergency Sealing vs Routine Lubrication
Trunnion Ball Valve Seat Injection: Emergency Sealing vs Routine Lubrication Quick answer: Trunnion ball valve seat injection can provide a route for an approved sealant to help control seat leakage. It does not automatically mean the valve needs routine greasing. Some designs permit planned lubrication or cleaning through dedicated passages; others treat injection primarily as […]
Trunnion Ball Valve Design Guide: Seats, DBB, Cavity Relief, Torque and Pipeline Selection
Trunnion Ball Valve Design Guide: Seats, DBB, Cavity Relief, Torque and Pipeline Selection A trunnion mounted ball valve is a quarter-turn isolation valve in which the ball is mechanically supported rather than allowed to move freely between the seats. That fixed-ball arrangement changes how pressure loads are carried, how the seats create sealing force, how […]
