The valve's brass body, brass\nvalve seat, and the zinc plated steel spring resist corrosion and can be used\nin operating temperatures up to 250 degrees F. The preset relief pressure is\naccurate to within +\/- 3 percent and a silicon O-ring provides a leak-proof\nseal to within +\/- 10 percent of the relief pressure. This safety valve is\nAmerican Society of Mechanical Engineers (ASME) safety rated and displays the\nUV mark for pressure vessel safety valves. It also displays the NB mark for\ncertification in accordance with NB-501, National Board Certification of\nPressure Relief Devices. This safety valve has a 58 Standard Cubic Feet per\nMinute (SCFM) flow rate and is suitable for low capacity pressure relief\napplications such as in home construction air compressors. Relief valves\nremove excess pressure or vacuum from a system. The valve openings allow\nfluids or gases to escape to decrease pressure, and then close once the valve\nreaches the reseating pressure limit. They also relieve excess vacuum by\nopening to release a gas into the system and then closing after it reaches its\nlow-pressure limit. Some relief valves have an adjustment mechanism to set the\npressure where the valve opens, making it suitable for various applications.\nRelief valves are rated according to the volume of liquid or gas that can flow\nthrough them and the material that the valve is constructed from must be\nsuitable for the fluid or gas, which may be corrosive or at an extreme\ntemperature, in which it operates. Relief valves are used in a variety of\napplications, such as air compressors, petrochemical and chemical\nmanufacturing, natural gas processing, and power generation.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003ePLEASE NOTE: 1\/4\" MALE NPT THREADED INLET CONNECTION APPROX 0.54 INCHES OUTSIDE DIAMETER\u003c\/li\u003e\n         \u003cli\u003eBrass construction and stainless steel spring for corrosion resistance.
