Imported high-pressure solenoid valve-German Lake brand

Solenoid valve is a basic component of automation used to control fluids. It is an actuator and is not limited to hydraulic and pneumatic. Solenoid valves are used to control the direction of hydraulic flow. Factory mechanical devices are generally controlled by hydraulic steel, so solenoid valves are used.
Working principle
There is a closed cavity in the solenoid valve, with through holes at different positions. Each hole leads to a different oil pipe. There is a valve in the middle of the cavity and two electromagnets on both sides. , which side of the magnet coil is energized, the valve body will be attracted to that side, and the movement of the valve body is controlled to block or leak out different oil drain holes. The oil inlet hole is normally open, and the hydraulic oil will enter different oil drain holes. The oil drain pipe is connected to the oil drain pipe, and then the pressure of the oil pushes the oil-filled piston. The piston drives the piston rod, and the piston rod drives the mechanical device. This controls the mechanical movement by controlling the current flowing through the electromagnet

Working principle of imported high-pressure solenoid valve
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 When the power is off, the pilot spool 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.
Product performance 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 life. There is no direct friction between the piston and the metal valve cavity. The valve body Installed with unlimited special energy-saving coils, it is not easy to burn out and restart after long-term stop. The action is also sensitive and has the lowest starting working pressure
