Product introduction:
The trunnion ball valve is also called the trunnion ball valve. It is a new generation of high performance ball valve. It is suitable for long-distance pipelines and general industrial pipelines. Its strength, safety and harsh environment are specially considered during design. A corrosive and non-corrosive medium. Compared with the floating ball valve, when working, the force generated by the fluid pressure on the ball before the valve is transmitted to the bearing, and the ball is not moved to the valve seat, so the valve seat does not withstand excessive pressure, so the ball valve is fixed. Low torque, small seat deformation, stable sealing performance and long service life, suitable for high pressure and large diameter applications. Advanced spring pre-seat assembly with self-tightening for upstream sealing. Each valve has two seats that seal in each direction, so the installation has no flow restriction and is bidirectional. This valve is generally installed horizontally.
