Chief Features：
Compared with floating ball valve, when working, all the forces generated by the fluid pressure in front of the valve on the ball are transmitted to the bearing, which will not make the ball move towards the valve seat, so the valve seat will not bear excessive pressure.And the torque of trunnion ball valve is small, the valve seat deformation is small, the sealing performance is stable, and the service life is long, which is suitable for high-pressure and large-diameter occasions. Advanced spring pre-seat assembly with self-tightening feature realizes upstream sealing. Each valve has two seats, which can be sealed in each direction. Therefore, there is no flow restriction for installation, and it is bi-directional. The valve is generally installed horizontally.
A variety of soft seal and hard seal seat materials to meet more process conditions
According to your requirement the valve can meets NACE standard, fugitive emission function and fire test certification of API Spec 607
The seat can be designed with double or single piston and has lower operating torque
All valves have self cavity pressure relief function to ensure the safety of the pressure in the middle chamber
