Air compressor safety valves are vital to the safety of the compressor, and person operating it. The safety valve is designed to release pressures at a set PSI in order to maintain the integrity of the pump, tank, and other components. Safety valves come in various PSI ratings and thread sizes. During normal operation and use, the safety valves may weaken and start to unload pressure at a level less than the indicated PSI. When this happens, it is time to replace your safety valve, and should be done as soon as possible. We stock a variety of sizes and psi ratings, and can help get you running safely, as quickly as possible. Call or stop in today if you need a new safety valve or any other part for your compressor.
