The working principle of the solenoid valve, solenoid valve,thereare sealed chamber, in different locations with holes, eachholeleads to a different pipeline,
the middle valve chamber, two is two electromagnets, which facethemagnet coil body will be attracted to the power which side,
by controlling the body's movement to a different file liveorleaked oil discharge hole, and into the hole is always open,
hydraulic fluid will enter a different row of tubing, thenoilpressure to push the oil just the piston,
the piston and drive the piston rod drive mechanism moving.Thiscurrent through the control solenoid to control themechanicalmovement
