A relief valve is designed to control the pressure in a system. The 3/4" 150 PSI Poly Relief Valve releases some of the pressure by allowing pressurized fluid to flow out an auxiliary passage. The high chemical resistance makes this product a good choice for a variety of liquids. You may be able to use this valve in a commercial, industrial or agricultural setting.

302 S.S. spring and EPDM O-Ring, excellent chemical resistance, 1/4" port for pressure gauge pipe plug included. Bypasses excess liquid. Adjustable to maintain control of line pressure at any pressure within the valve's operating range. Selected pressure setting firmly held in place by locknut. Extra large valve passages to handle large flows.
