500X PRESSURE SUSTAINING OR RELIEF VALVE DN50~DN300



The valve can not only use as pressure relief valve, but also as a pressure holding valve by the main valve using hydraulic automatic operation. The valve as a pressure relief and holding valve, can maintain the water pressure below the safe value. It can also keep the upstream pressure of the main valve above the setting value to maintain the upstream water supply pressure.
