Solenoid valve for cast iron water flange DF series

DF SeriesWater Solenoid ValveApplicable to water or liquid as the working medium, can automatically control or remote control of air, water, oil liquid and other working media pipeline on and off. As DFsolenoidsRubber sealing, so the cleanliness of the working medium is greatly reduced. With rapid opening and closing, high reliability. Water solenoid valve for the second open valvePilot Operated Solenoid ValvesThe structure is mainly composed of pilot valve and main valve, and the main valve adopts rubber sealing structure. Normal position, the movable iron core sealed pilot valve mouth, the pressure balance in the valve cavity, the main valve mouth closed. When the water solenoid valve coil is energized, electromagnetic force will be active core suction, the main valve cavity of the medium from the pilot valve port leakage, so as to produce a pressure difference, the diaphragm or the valve cup was quickly raised, the main valve opening, the valve is open, the valve will be in the way state. When the coil is de-energized, the magnetic field disappears, the movable iron core reset, closed the pilot valve port, the pilot valve and the main valve cavity pressure balance, the valve is closed.
