700X Pump Control Valve

700X Pump Control Valve Brand: Gold Titanium Valve Model: 700X Nominal Diameter: DN50 ~ DN400 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, pump control valve Product Introduction 700X Pump Control Valve, is an installation at the pump outlet to prevent the media back of the check type valve. When the pump is about to stop before the water supply valve to close about 90 percent ahead slowly to avoid a sudden stop the pump and produce water hammer and water hammer sound, when the pump is completely stopped, the valve is completely closed to prevent backflow of water pumped out of the effective protection pumps, impact arising from the reversal reflux. The product is essential for the pump outlet protector. Valves streamlined design for accurate and closed by the pilot solenoid valve, safe and reliable, effectively prevent water hammer and water hammer sound, long life, easy installation and maintenance. 2, pump control valve works when the pump is working to downstream water supply valve, solenoid pilot valve is fully open, transferred to the appropriate degree of opening of the needle valve upstream water through the needle, the pilot valve, the check valve into the main valve control room, the electromagnetic pilot valve outflow, then the main valve control room pressure is maintained at the proper degree of opening of the main valve to maintain normal water supply downstream. When the pump stops working, turn off the solenoid pilot valve, the main valve to stop the drain, the main valve chamber pressure increases, the main valve begins to close, when close to 90%, the main valve to stop the pump the upper limit switch output signal, the pump stops running, this When the main valve downstream water through the check valve into the main control room, control room pressure increases, the main valve closed.
