Function Principle

   The valve has three ports, which can be reversing and mixed function to replace two pieces globe valves. When the valve is in non-working condition, the valve C port is often closed due to the force of spring When the actuator piston is compressed, the valve C port is opened and the B port is closed. When double acting, the valve opens and closes with compressed air.
