The valve is normally closed and it uses the pipeline pressure to open and close the compressed air flow.

If not piloted, with a minimum pressure of 2 bar the valve transits from closed to open position spontaneously. The valve is fully open with pipeline pressure around 3.5 bar.

If pressure drops under 2 bar the valve automatically closes. This is the minimum pressure that remains in pipeline sections not affected by failure.

The pipeline pressure is always available on the outlet “Pilot Pressure”. Using a pneumatic or electropneumatic deflector is possible to flow this pressure to the “Closing Port” in order to close the valve immediately.
