Imported high-pressure internal thread solenoid valve-German Lake brand

Guolak
brand,
imported high-pressure internal thread solenoid valve
widely used in aerospace, shipbuilding industry, petrochemical industry, water supply and drainage, fire-fighting equipment, food and medical equipment, cleaning equipment, landscape sprinkler irrigation, humidification Equipment, hydraulic equipment, testing equipment, water plants, etc., the working pressure is in the pipeline system.
Product Features
The valve cores are all stainless steel piston type. The piston ring will not be stuck by impurities in the medium. It has high dynamic sealing performance and long service life. There is no direct friction between the piston and the metal valve cavity. , the valve body is installed with an unlimited custom-made coil, it is not easy to burn out and restarts when stopped for a long time, and the action is equally sensitive with the lowest starting working pressure

Working principle
Normally closed When the coil is energized, the pilot valve core is closed, the pilot hole is opened, the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened. When the coil is deenergized, The pilot valve core is restored by the spring, the pilot hole is closed, the valve chamber is pressurized by the piston orifice and the thrust of the return spring, and the solenoid valve is closed.
Normally open When the coil is energized, the pilot hole is closed, the upper cavity 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.

Special functions
Ordinary type (other functions can be customized)
If the pressure at the outlet is greater than the pressure at the inlet, the medium will conduct in the opposite direction. A check valve can be installed or a valve with its own check function can be customized.
