The ST25 Series are 1/4 in NPT ASME safety valves for small air compressor systems and other related applications. It is compact in size but has a high flow capacity; a resilient rubber pad ensures the valve is bubble-tight to within 10% of set pressure. Stamped with UV and NB symbols. Available in three set pressures: 200, 300, and 350 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.
