The SB50 Series are 1/2 NPT high-capacity ASME safety valves with a unique O-ring ensures the valve is bubble-tight to within 10% of set pressure. Pressure tolerance: ±3%. Available in two set pressures: 165 and 200 psi.
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.
