The R-K BPR (Back Pressure Regulator) series is designed to control the up-stream pressure of the piping system from any change of its back-pressure due to the close of any component or sub-systems. The BPR will prevent pumps from Dead head, over pressure, pressure surges, and maintains back pressure in closed loop systems. Adjustable screw and lock-nut makes it easy and accurate preset pressure. Teflon (primary) and elastomer (back-up) diaphrams.
No metal contact with fluid. Wide pre-set pressure range (10-120 PSI) Small pressure differential band from cracking point to fully open, and from widely open to close. Top entry makes in-line maintenance quickly and easily Ideally for DI water, harsh chemical, and other high purity applications.
