Pneumatic ON-OFF ball valve

Pneumatic on-off ball valve consist of pneumatic piston actuator and ball valve. Simple structure, rapid switching, large flow capacity, zero leakage, applicable to the fluid with high viscosity, fiber-containing, solid particle. It has been widely used in petrochemical, metallurgy, light industry and other industrial automation field to cut-off or open the gas / liquid transport pipeline.
