The EX/ATEX conformed valve is physically very similar to the ‘standard’ Pinch Valve, keeping many of the main advantages. In fact the only real visible differences are the lock teeth washers and the earth connection. The washer teeth are used on the flange bolts to give full contact to the aluminum body through the paint. This ensures the electrical current to pass through the Pinch Valve if required.
