Safety relief valve piston 500X

500X piston safety relief valve holding pressure Brand: Gold Titanium Valve Model: 500X Nominal diameter: DN500 ~ DN800 Nominal pressure: 1.0 ~ 4.0Mpa Suitable medium: water, oil Suitable temperature: 0 ~ 80 ℃ Connection: flange material: cast iron, cast steel, ductile iron, stainless steel 1, piston late pressure safety relief valve piston 500X Introduction safety relief, pressure valve, is a stable upstream pressure on the valve of a special solid, based on actual usage, previously set at a fixed value on the pilot valve, when the upstream pressure is higher than the set value, the pilot valve automatically opens, the piston chamber pressure is reduced, the main valve is opened. Upstream pressure relief valve to maintain stability. 2,500X piston safety relief valve works do relief valve, when pilot valve to adjust the pressure relief valve condition, water through the needle valve, the main valve control room, ball valves A, pressure relief / holding pressure pilot valve, ball valve B the flow of exports, this time, the main valve is turned on, when the inlet pressure exceeds the safety value set by the pilot valve, the pressure relief valve opens automatically to release some water through the valve C, allowing the line drain. When piping to a safe value, pressure relief valve closes automatically, do the relief valve, each valve normally open. Do hold pressure valve, when pilot valve adjustment pressure valve status for as long as the main valve inlet water pressure below the set pressure the pilot valve, pilot valve that is closed and the main valve control room pressure increases, the main valve closed. When the main valve when the upstream pressure exceeds the set pressure of the main valve, the main valve to open, the control room of the water through the drain valve to the outlet, the control room pressure, the main valve to open, start the water supply, namely the protection of the upstream water pressure, so pressure valve , normally closed valve or plugs replaced. 3, piston holding pressure safety relief valve connection size DN 500 600 700 800 L 1075 1230 1300 1450 H1 620 695 930 950 H2 750 850 1120 1150 Zhejiang specializes in producing titanium valves hydraulic control valves, valve, regulator valve, tube power valve, micro-resistance ease closure check valve, flow control valves, hydraulic automatic valves, intelligent automatic control valve, butterfly valve, mud valve, head-rotary valve and other products, widely used in high-rise buildings, fire, waterworks, power plants, metallurgical, petrochemical, coal, energy, food, medicine and other water distribution piping system.
