ZSHTR-320 Pneumatic High-Pressure O-Type Ball Valve is a rotary ball valve with a 90-degree angle of operation. It consists of a pneumatic cylinder actuator and a high-pressure O-type ball valve assembly. The valve core adopts a fixed structure design, requiring low operating torque, while the valve seat utilizes a floating embedded structure to ensure excellent sealing performance.
The actuator employs a GT high-performance pneumatic piston actuator, which features a simple structure and delivers high output torque. This ball valve is suitable for controlling high-pressure or high-pressure differential fluids containing fibers and solid particles.
