ZCST series solenoid valves parameters Technical Overview: ZCST Solenoid Product Use: Johnson Controls selected for the on-off valve to the water or liquid as the working medium, automatic control or remote control of water, oil, liquids and other working media pipeline. As the valve with rubber seal, so the cleanliness of the working medium is greatly reduced, with open and close rapidly, and high reliability. ZCST solenoid valve product principle: The valve is opened for the second pilot valve solenoid valve, its structure is dominated by the composition of the pilot valve and the main valve, the main valve with rubber seal structure. Regular position, the movable core sealed pilot valve orifice, pressure balance valve chamber, the main valve port closed. When the coil is energized, the electromagnetic force on the active core pull, the main valve cavity media self-guided valve port leakage, as well as a pressure difference, diaphragm or valve cup was quickly lifted, opening the main valve to open, the valve was then pathway of. When the coil is de-energized, the magnetic field disappears, the movable core is reset, the pilot valve closed mouth, after the pilot valve and the main valve chamber pressure balance valve was closed again. Technical parameters: 1, ambient temperature: 0 ~ + 50 ℃ 2, Suitable medium: water (no large particles of impurities) 3, the maximum working pressure: 0.4Mpa (special requirements: 0.8Mpa) 4, the minimum working pressure: 0.05Mpa 5, Power supply: AC: 380V, 220V, 110V, 48V, 36V, 50Hz, DC: 220V, 110V, 24V, 12V power supply allows fluctuations: -10% to + 10% 6, Power: AC: 20W DC: 18VA 7, media Temperature: 0 ~ 60 ℃ 8, opening and closing time: 150ms ~ 200ms / times 9, the product has an automatic drain valve, filter functions, with fully enclosed waterproof coil.
