DVD 430 Pressure Relief/Sustaining Valve is a hydraulically operated & diaphragm-actuated control valve. It consists of a pilot for pressure sensing and a main valve. It can perform two main functions depending on the installation of the valve. If it is connected to the line, it perfoms as a pressure sustaining valve, which sustains the upstream pressure regardless of fluctuating flow or varying downstream pressure. If it is connected to a circulation line to the suction reservoir, it perfoms as a pressure relief valve, which releases excessive system pressure back to the suction reservoir in case maximum pre-set pressure is exceeded. As a result, the user can always get a constant pressure from the pump without wasting water.
