Pneumatic piston two-stage cut-off ball valve is a type of cut-off ball valve that can achieve two opening or two closing actions. It consists of ball valve, piston actuator, solenoid valve, one-way valve, quick exhaust valve and other components. Due to the fast exhaust and throttling function of the actuator, the two-stage ball valve has excellent switching characteristics, which slows down the opening and closing speed of the valve, makes the fluid change in the pipeline smooth, and will not cause water hammer phenomenon and explosion of flammable fluids due to impact, nor will it damage the flow meter and other instruments in the system due to impact. Therefore, it is used in flow control systems in industries such as petroleum, chemical, light industry, national defense, etc., and is particularly suitable for oil storage and transportation systems.
