Normally Closed Solenoid Pneumatic Valve / Thread Water Solenoid Valve 1/2"
The valve is a two-way valved water inlet solenoid valve, the structure of which is mainly composed of a pilot valve and a main valve, and the main valve adopts a rubber sealing structure.The 2s series normally closed solenoid valve is made of stainless steel and is more durable. Suitable for air, compressed air, water, oil and other media, low noise, high reliability, can work normally in extreme environments.

Inlet water solenoid valve working principle
When the position is normal, the movable iron core seals the pilot valve port, the pressure in the valve chamber is balanced, and the main valve port is closed. When the coil is energized, electromagnetic force is generated to suck the movable iron core, and the medium in the main valve chamber of the water inlet solenoid valve is leaked from the pilot valve port, so that a pressure difference is generated, the diaphragm or the valve cup is quickly lifted, and the main valve port is opened. The valve is in the path. When the coil is de-energized, the magnetic field disappears, the movable iron core is reset, the pilot valve port is closed, and the pressure in the pilot valve and the main valve chamber is balanced, and the valve is closed again.
There are closed chambers in the inlet solenoid valve. There are through holes in different positions. Each hole leads to different oil pipes. The middle of the cavity is a valve. On both sides are two electromagnets. Which side of the magnet coil is energized? Which side is attracted to, by controlling the movement of the valve body to block or leak different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then pushed by the pressure of the oil The piston of the cylinder, the piston drives the piston rod, and the piston rod drives the mechanical device. This controls the mechanical motion by controlling the current of the electromagnet.
