guangzhou atech valve co

Germany Leike (
) brand imported water solenoid valve application scope
It is widely used in aerospace, shipbuilding industry, petrochemical industry, industrial furnaces, boilers, water supply and drainage, heating and air conditioning, fire protection equipment, drying equipment, In pipeline systems such as food medical equipment, cleaning equipment, landscape sprinkler irrigation, water plants, etc.
Features of the solenoid valve for imported water
Pilot-operated structure, the valve core is made of stainless steel pistons, the piston rings will not be stuck by impurities in the medium, the dynamic sealing performance is high,
The piston has a long life There is no direct friction with the metal valve cavity. There is no limit to the installation direction of the valve body. The custom-made coil is not easy to burn out and restart after a long stop. The action is also sensitive and has zero leakage. The service life is more than 10,000 times.

Working principle
Normally closed when the coil is energized When , the pilot spool is closed, the pilot hole is opened, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened. When the coil is powered off, the pilot spool is reset by the spring, the pilot hole is closed, and the upper chamber of the valve is opened. The piston orifice is pressurized and the solenoid valve is closed by the thrust of the return spring.
Normally open When the coil is energized, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return spring, and the solenoid valve is closed. When the coil is powered off, the pilot valve core returns by the spring, the pilot hole opens, the upper chamber of the valve relieves pressure, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens.
