Product Description
Trunnion ball valves are resuitable for use on various kinds of pipelines of Cl ass 1 50~Cla ss 2500, PN1 6~PN1 60, JIS 10K~JIS 20K to cut off or turn on the pipeline medium, of which the operation types include worm gear, manual, pneumatic or electric actuators, being in general of flange connection, and butt welding ends connection as well.
Trunnion ball valve with the Bi-sealing design structure, i. e. Seat sealing in front of the ball and seat sealing behind the ball
Regarding the seat after the ball, the piston effect formed by the area difference between D2 and D3, plus the pretightened force of aspring would cause the seat behind the ball to touch the ball closely to form the tightness, of whic h the sealing force will become bigger as the pressure difference gets higher.
Blow-out proof stem
Blow-out proof structure is provited with for the stem, which is positioned by the up-end cap and screw, being guaranteed not to be blown-out by the medium even if at abnormal risen pressure in the cavity.
Anti-static design
The ball of the trunnion ball valve gets close contact with each othe through the trunnion, adjusting cushion, and down-end cap, the passage of static electricity thus forms together with the valve, which may lead the static electricity caused by sparks generated by friction between the ball and seat during on and off performance to the ground to prevent the possible risk of fire or explosion.
