Zhejiang 300X slow closing check valve piston

300X slow closing check valve piston Brand: Gold Titanium Valve Model: 300X Nominal diameter: DN500 ~ DN800 Nominal pressure: 1.0 ~ 4.0Mpa Suitable medium: water, oil Suitable temperature: 0 ~ 80 ℃ Connection: France blue material: cast iron, cast steel, ductile iron, stainless steel 1, piston slow closing check valve Description Piston slow closing check valve, the valve with a hydraulic control principle to achieve top and bottom of the piston itself through the pipeline medium pressure motion, thereby controlling the opening and closing of the main valve, the hydraulic control valve main valve disk closed speed, it is by adjusting the opening of the outlet valve to achieve. I produced 300X limited to DN500 diameter piston valve above it, DN500 caliber Here is the diaphragm. 2, piston relief valve closed scope petrochemical, construction, water, fire, chemical, coal and other 300X slow closing check valve piston works when the valve from the inlet end of the water supply, water through micro-filters, needles type valve, check valve into the main control room, after the drainage valve downstream, since the needle valve opening is less than the small opening, that is the main water valve control chamber drain faster than the speed, therefore reducing the pressure control chamber acting on the main the lower end of the inlet pressure valve plate to open the main water valve to West. When the pipe to stop water supply, downstream water began to return, some of the water through the valve into the control room, the one-way valve effect, the water can not flow back from the main control room, causing the main valve control room gradually boost, slowly close the main valve. 3, piston slow closing check 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, pipe 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, water plants, power plants, metallurgical, petrochemical, coal, energy, food, medicine and other water distribution piping system.
