Solenoid hydraulic valve

Generally speaking, the operation principle of solenoid hydraulic valves is similar to solenoid pneumatic control valves. The main difference is that the solenoid hydraulic valve controls the flow of hydraulic fluid, and the hydraulic pressure is usually about 3000 psi (210 bar, 21 MPa, 21 MN/m2). In the aviation manufacturing industry, hydraulic machinery uses solenoids to control hydraulic fluid actuators, giving actuator sufficient power to bend titanium plates.

Solenoid operated valves are often used in agricultural irrigation systems. Here, use a very cheap small size solenoid to turn on or close a small pilot valve to allow a small amount of water to be applied to the piston. The latter is mechanically coupled to the main valve and has enough power to switch the main valve.

The transmission solenoid (transmission solenoid) depends on the electromechanical force to adjust the flow of the hydraulic fluid through the automatic transmission. The clutch solenoid is usually mounted inside the valve body of the transmission.
