NEW 1/4" BRASS 165 PSI AIR COMPRESSOR SAFETY RELIEF POP OFF VALVE

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 64 Standard Cubic Feet per Minute (SCFM) flow rate and is suitable for low capacity pressure relief applications such as in home construction air compressors. Relief valves remove excess pressure or vacuum from a system. The valve openings allow fluids or gases to escape to decrease pressure, and then close once the valve reaches the reseating pressure limit. They also relieve excess vacuum by opening to release a gas into the system and then closing after it reaches its low-pressure limit. Relief valves are rated according to the volume of liquid or gas that can flow through them and the material that the valve is constructed from must be suitable for the fluid or gas, which may be corrosive or at an extreme temperature, in which it operates. Brass construction and stainless steel spring for corrosion resistance. 250 degrees F maximum temperature for use in high temperature applications ASME safety rated with UV and NB marks
