Control Devices ST25-1A250 ST Series Brass Soft Seat ASME Safety Valve, 250 psi Set Pressure, 1/4 Male NPT

This Control Devices ST25-1A250 ASME safety valve has a brass body, a 250 psi relief pressure, a 1/4 inch male NPT threaded inlet connection, and a stainless steel pull ring for manual pressure relief. The valve's brass body, brass valve seat, and the zinc plated steel spring resist corrosion and can be used in operating temperatures up to 250 F. The pre-set relief pressure is accurate to within +/- 3 percent and a silicon O-ring provides a leak-proof seal to within +/- 10 percent of the relief pressure. This safety valve is American Society of Mechanical Engineers (ASME) safety rated and displays the UV mark for pressure vessel safety valves. It also displays the NB mark for certification in accordance with NB-501, National Board Certification of Pressure Relief Devices. This safety valve has a 219. 8823 cubic feet per minute (CFM) flow rate and is suitable for pressure relief applications such as in home construction or industrial air compressors.
