Zhejiang factory direct AX742X diaphragm safety relief valve

AX742X diaphragm safety relief valve Brand: Kim titanium valves Model: AX742X Product name: holding pressure safety relief valves, piping with pressure relief valve, pressure relief valve wholesale prices, pressure relief valve holding pressure principle Nominal Diameter: DN50 ~ DN600 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 AX742X diaphragm safety relief valve Product Description Relief holding pressure valve is usually installed in the pipe-rise buildings, fire water system and other water supply system, water supply system piping when pressure exceeds the set pressure, the pressure relief valve automatically enable the rapid relief, protection of pipeline safety, but also can be delayed pressure valve to protect the main valve upstream water pressure once overpressure relief valve quickly open and timely relief. Close steady, eliminate stress aftermath. AX742X diaphragm pressure relief valve works when the pipe end when the water supply from the water, the water flow through the needle into the main valve control room, the outlet pressure to the pilot valve through the catheter effect, when the pilot valve outlet pressure is higher than the set value, the guide valve is closed, the control room to stop the drain, then the main valve control room pressure rise and close the main valve to stop the water supply. When the pilot valve outlet pressure drops below the set pressure, the control room to the downstream drainage, since the displacement of the pilot valve is larger than the needle into the water, the main valve control room pressure drops, the inlet pressure of the main valve is open, a steady state, the control room water, drainage same opening degree constant outlet pressure do not, regulating pilot valve spring to set the outlet pressure. AX742X Diaphragm design pressure relief valve holding pressure valve design and manufacture of standard reference: the standard length of the structure specified GJ / T167-2002 valve according to corporate standards and customer flange connection dimensions according to GB / T9113.1-2000 regulation valves by provisions valves GB / T12220-1989 pressure test accordance with the provisions GB / T13927-1992 of AX742X diaphragm technical parameters Nominal pressure relief valve test pressure Mpa Mpa housing seal test pressure Mpa pressure range Mpa Applicable media application temperature ℃ 1.0 1.5 1.1 0-1.0 Water 0 ~ 80 1.6 2.4 1.76 0-1.6 2.5 3.75 2.75 0-2.5 AX742X diaphragm safety relief valve connection size DN 50 65 80 100 125 150 200 250 300 350 400 450 500 600 700 800 900 1000 L 205 215 245 290 350 415 457 535 610 660 690 750 855 990 1030 1085 1110 1250 H 30 337 467 520 481 580 640 778 889 1010 1037 1264 1294 1324 1600 1750 1900 2100 titanium valves Zhejiang is a professional production, manufacture and sales ten years, with a senior technical experience, the company has consistently execute [product quality assurance, excellence, professional building world-class technology, is a common choice of major merchants] The company mainly produces 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.
