Trunnion mounted ball valve

Trunnion mounted ball valve is applicable to long distance 

pipeline and general industry pipeline. Its strength, safety

and harsh environment resistance shall be taken into special 

consideration, therefore, it can be applied to corrosive and 

non-corrosive medium. When operation, the acting force 

produced by valve front end fluid on ball can fully pass to 

bearing without moving ball, and the ball will not move to

valve seat, in this way, valve seat will not bear greater 

pressure; therefore, trunnion mounted ball valve is 

characterized as low torque, small valve seat deformation,

stable sealing performance,long-term service life. It is used

to high pressure and large bore application. With tight property,

advanced spring pre-valve assembly can realize upstream seal. 

Every valve is equipped with two valves and sealed from per

direction; therefore, there is no flow direction limitation for

installation and it can be bi-directional application. This valve

is usually installed horizontally.
