DF Cast Iron Solenoid Valve

 DF Cast Iron Liquid Solenoid Valve

 DF Cast Iron Liquid Solenoid ValveDF Liquid Cast Iron Water Solenoid Valve is the use of electromagnetic force to achieve the valve on and off the two - way automatic valve.It is the basic element to realize the automatic control of all kinds of gas and liquid pipelines with compressed air, clean water and low viscosity, no suspended substance and no corrosive medium.It can be widely used in automatic control system of machinery, metallurgy, electric power, chemical industry, textile, petroleum, light industry, transportation, national defense, scientific research and other departments.

Liquid Cast Iron Water Solenoid Valve is adopted pilot automatic control structure, compact structure, small volume, reliable action, excellent sealing performance, easy to use and maintenance.

After the coil energized, namely the formation of magnetic field, under the action of magnetic field, sucking up the iron core, open the pilot valve mouth, due to import the orifice is smaller than the guide valve mouth, at this point, the upper rubber diaphragm pressure is reduced, in under the action of working medium, the main valve opens, forming pathway, power outages, moving iron core reset by spring force and so on, close the pilot valve and the upper diaphragm pressure, the differential pressure function, immediately shut off the main valve.
