Also called a 500 x 500 x relief valves, pressure holding pressure valve, the main valve, pressure holding pressure pilot valve, needle valve, ball Industrial Valves, micro shape filter and pressure gauge of hydraulic control of system. The valve using hydraulic automatic operation, can make a relief valve and can be used for holding pressure valve, and do not need other devices and energy, maintenance is simple, one valve is multi-purpose. 500 x relief valve working principle 1, A pressure relief valve: when the pressure relief/holding pressure pilot valve is adjusted for pressure condition, water through the needle valve, the main valve control room, ball valve, A pressure relief/holding pressure pilot valve, ball valve B of exports, at this time the main valve is fully open. When the inlet pressure exceeds the pressure relief/holding pressure pilot valve set TVC, pressure pilot valve will automatically open, channelled through ball valve C section water, make the line pressure. When the pressure recovery to TVC, pressure relief valve automatically shut down. As a pressure relief valve, ball valve normally open. 2, for holding pressure valve: when the pressure relief/holding pressure pilot valve adjustment of the state, as long as the main valve import water pressure is lower than the pilot valve set point, pilot valve is closed. The main control room booster, the main valve closed. When the main valve upstream water supply pressure exceeds pilot valve set pressure, holding pressure pilot valve to open, the control room of water through the ball valve to the export, the control room main reducing valve open, began to water supply, that maintain the upstream water pressure. For holding pressure valve, ball valve normally closed C or substituted a plug. 500 x relief Industrial Valves structure

500 x 1 characteristics of pressure relief valve. Novel structure reasonable, reasonable by using the principle of the hydraulic control theory; 2. High sensitivity, safety relief; 3. The disc fast slow down closed, no water hammer shock; 4. Smooth operation, no noise; 5. Long service life. 500 x relief valve applicable scope is widely used in urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection, 500 x relief valve manufacturer recommendations
