Best Hydraulic Solenoid Valve by GGHYD

The hydraulic solenoid valve has a cavity airtight with through-holes on different positions, each hole connects to different oil pipes. The plunger is in the middle of airtight, and two solenoids on both sides of the plunger. 

Once one of the solenoid coils is charged, the valve will move to the same side. In a word, the movement of the hydraulic solenoid is the key to start or close various oil outlets.

Indirect operated hydraulic solenoid valve (additionally called servo operated, or pilot operated) utilizes the differential weight of the medium over the valve ports to open and close. Generally, these valves need a base weight differential of around 0.5 bar. 

The bay and outlet are isolated by an elastic film, likewise called a stomach. The film has a little gap with the goal that the medium can stream to the upper compartment. The weight and supporting spring over the layer will guarantee that the valve stays shut. The cylinder over the film is associated with a little channel to the low weight port. This association is hindered in the shut position by a solenoid.
