This component is a crucial overpressure protection device integrated into compressed air systems. Specifically calibrated to activate at 125 pounds per square inch (psi), it functions by automatically venting excess pressure from the air tank. For instance, should an air compressor’s pressure switch fail, this valve will open to prevent the tank from exceeding its safe operating limit.
The strategic inclusion of this safeguarding mechanism is paramount to ensuring the safe and reliable operation of compressed air equipment. Its benefit lies in mitigating the risk of catastrophic tank rupture or system failure due to over-pressurization. Historically, the implementation of such valves has significantly reduced workplace accidents and equipment damage associated with compressed air applications. The presence of a properly functioning valve is a cornerstone of responsible compressed air system management.
