Pneumatic ON-OFF Ball Valve
Pneumatic on-off ball valve consists 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.
