Pressure Relief Valve with set pressure of 3988 psi (275 bar). 1/8 in male NPT thread.
A Pressure Relief Valve (also known as a Safety Valve, Overpressure Relief Valve, or simply a Relief Valve) limits the amount of pressure in a compressed gas system. Without such a valve in place, pressure could build up beyond what the system is designed for and cause equipment failure. The Pressure Relief Valve opens at a designed “set pressure” to protect the system against failure from being overpressurized. This valve has a designed set pressure of 3988 psi (275 bar).
