DRV Series Low Pressure Diaphragm Relief Valve

The Simtech DRV Series Low Pressure Diaphragm Relief Valve is designed for low pressure applications with no back pressure to release excess up-stream pressure on the piping, storage tank and/or system due to pressure surges, vaporizing, or heat reaction.  Adjustable screw and lock-nut makes it easy to accurately pre-set relief pressure. This pressure relief valve is designed to keep the stainless steel spring totally isolated from the fluid chamber insuring no metal contact with the fluid.
