Normally Closed – Air to open – Spring Return
The best valve for silo safety systems – Also available in Food Quality
How it works:
The normally closed Pinch Valve operates in the opposite way to the standard Pinch Valve. Air pressure is used to open the valve and when the air is taken off the valve closes in the fail safe position. When open, the Normally Closed Pinch Valve allows full unobstructed flow.
