Product introduction

Pneumatic ball valve is a ball valve that drives a valve switch through a pneumatic actuator. It includes a floating ball valve and a 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 designed for various corrosive applications. And non-corrosive media. Compared with the floating ball valve, the trunnion ball valve transmits all the force generated by the fluid pressure on the ball to the bearing during operation, and does not move the ball to the valve seat, so the valve seat does not withstand excessive pressure, so it is fixed. The ball valve has small torque, small deformation of the valve seat, stable sealing performance and long service life, and is 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. Floating ball valves are generally small diameter valves for low pressure piping.
