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.
