Hydraulic Automatic Electric Control Valve

Solenoid guide valve can realize the valve opening and closing remote control. With the addition device, the opening and closing speed can be controlled. When the valve from the mouth end feed water, water flow through the needle valve into the main valve control room, when the electromagnetic guide valve opened the control room water through the electromagnetic guide valve, ball valve out. Ball valve opening is greater than the needle valve opening, the main valve control room pressure is very low, the main valve is in full open state. When the solenoid valve is closed, the water in the control room of the main valve can not flow out, and the control room increases the pressure. Push the diaphragm to close the main valve. This product uses the pilot valve to control the valve opening and closing, saving energy. It can replace other large electric valve devices, widely used in high-rise buildings, living areas and other water supply system and urban water supply projects.   working pressure PN10, PN16 testing pressure shell: 1.5 times rated pressureseat: 1.1 times rated pressure working temperature -10 °C to 80°C (NBR)-10 °C to 120°C (EPDM) suitable media water   Main dimension table  DN 20 25 32 40 50 65 80 100 125 150 200 250 300 350 400 450 L 150 160 180 200 203 216 241 292 330 356 495 622 622 787 914 978 H1 179 179 179 210 210 215 245 305 365 415 510 560 560 696 735 677 H 342 342 342 395 395 406 430 510 560 585 675 730 760 840 910 1027     Products Detailes Process Application
