Simtech, SBR 401 4 005, SBR Series, 1/2" PP/EPDM Low Pressure Relief, Diaphragm Valve, FNPT Ends, Threaded
The SIMTECH SBR series diaphragm pressure relief valve is designed to protect piping and equipment from pressure changes where a rapid release of excess pressure is required. Prevents pumps from deadheading, over pressurization, pressure surge conditions, and maintains back pressure in closed-loop systems. Adjustable screw and locknut make it easy to accurately preset desired relief pressure. Teflon (primary) and EPDM (back-up) diaphragm standard. No metal contact with fluid. Wide adjustable relief pressure range (10-125 PSI) Small pressure differential band from cracking point to fully open, and from fully open to close. Top entry makes in-line maintenance quick and easy. Ideal for DI water, harsh chemical, and other high purity applications, as manufactured by SIMTECH.
Note: Teflon Internals Available for Non-Lubricant and Extended Cycle Life Applications
