How It Works
The regulator attaches to the inlet of the Pinch Valve. Since a Pinch Valve only requires 2.5-3BAR differential pressure to close, a regulator can be set to only allow this much pressure into the Pinch Valve.
For example, a compressor may blow 6 BAR or even up to 10 BAR air pressure into a Pinch Valve, which would cause stress to the rubber sleeve. A regulator controls how much air is allowed into the Pinch Valve, to ensure the best possible lifetime of the sleeve.
