We have an air compressor that is intended to be used for high pressure air tools (max. 400 psi). We use it to supply 200 psi air pressure to 2 small air bags for laboratory testing. It is left on for a few days at a time and whenever the air pressure drops, it kicks on to raise the tanks in the air compressor back up. We have the air compressor running to a reservoir tank, then through a precise valve where we control the air pressure, and then into the bags. The system has worked well thus far.
However, the problem occurs when we have an airbag break. This occurred over night and the air compressor ran for about 12 hours before someone found it. It was constantly trying to return the pressure to 200 psi while the airbag was just releasing the pressure out the other end. We are wondering if there is a regulator that would close the line permanently when this problem occurs. I was reading about back-pressure regulators, but this would just allow the air compressor to build back up, then it would release all of its air pressure, and then it would build back-up, it would still run continuously. We would like something that if the pressure in the line dropped to 100 psi, it would immediately close the line at this valve, and not re-open even after the air compressor re-gained its high pressure.
