Pneumatic fixed ball valve
The Pneumatic Fixed Ball Valve is a high-performance automated valve designed with a trunnion-mounted fixed ball structure and equipped with a pneumatic actuator for fast, reliable, and precise flow control. The fixed ball design provides excellent stability under high pressure and large diameter pipeline conditions, reducing operating torque and ensuring smooth operation.
The valve is widely used in critical pipeline systems requiring automatic shut-off, remote control, and high safety performance. It features a robust structure, double block and bleed function, low operating torque, excellent sealing performance, and long service life.
The pneumatic actuator enables quick response, easy automation integration, and reliable operation in harsh working environments. It is an ideal solution for oil & gas pipelines, petrochemical plants, power stations, chemical processing systems, and industrial fluid control applications.
