Solenoid Valve for Cast Iron Water Flange DF Series

DF series water solenoid valve is suitable for water or liquid as the working medium, can automatically control or remote control of air, water, oil and liquid and other working media pipeline on and off. As the DF solenoid valve using rubber seal, so the cleanliness of the working medium requirements are greatly reduced. With rapid opening and closing, high reliability. Water solenoid valve for the second opening of the pilot-operated solenoid valve, its structure is mainly composed of pilot valve and main valve, the main valve using rubber sealing structure. Normal position, the movable iron core sealed pilot valve port, the pressure balance in the valve cavity, the main valve port 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.

Important Notes

• The solenoid valve pipe diameter shall be maintained in a horizontal installation, with the coil installed vertically.
• This valve features a pilot-operated design with an opening pressure of two kilograms.
• Outlet piping with backflow requires a check valve.
• The medium must be clean and non-corrosive (suitable for water or compressed air).
• This coil is not suitable for outdoor use. For outdoor applications, please select an outdoor waterproof coil.
• It is recommended to keep the power on for no more than one hour at a time. If extended power supply is required, please select a coil equipped with an energy-saving module.
