Features

SD-RV20CA Pressure Relief Valves are spring operated lead free brass relief valves designed to be used only as protection from the build up of excessive pressure in systems containing water, oil or air. These valves are not ASME approved safety relief valves and should not be used in system applications with this requirement. They feature a lead free brass construction with stainless steel springs. Ideally suited as a bypass thermal expansion relief valve, the SD-RV20CA valves incorporate a calibrated adjustment feature for setting the valve to the relief pressure required.
