Back Pressure Relief Valve

The RCAF is an adjustable combination back pressure and relief valve that will give you the best chance to keep a constant flow to your on-line analyzers. The RCAF has large internal passages and an innovative adjustable wave spring/diaphragm design to ensure better pressure control over a wide range of flows. And the top works can be disassembled without the danger of a highly compressed spring which could cause injury.

The capability to act as a relief valve eliminates the need for a second relief valve (‘pop-off’) that is prone to sticking in the open position and venting precious sample to a drain header WITHOUT YOU EVEN KNOWING ABOUT IT.
