Structure and working principle
WE type solenoid directional valve adopts wet type AC or DC electric magnet. The valve is controlled by the solenoid to control the different working positions of the spool. When the solenoid is de-energized, the spool is kept in the middle or terminal position by spring pressure (except for pulse type valve). When the solenoid is energized, the spool is pushed to the working position and returns to the initial state when the power is cut off. At this point the spool can be moved by pushing the fault check button by hand.
As the wet solenoid internal and return oil cavity, so that the armature oil to move, can reduce wear and tear, cushioning, and improve the heat dissipation performance, improve the service life. AC solenoid has short action time, simple electrical control line, no special contact protection and other characteristics. DC solenoid is soft switching characteristics, high frequency of action, insensitive to overload or low voltage response, reliable work.
WE type directional valve is a slide valve type directional valve controlled by solenoid, which is mainly used to control the on-off and flow direction of liquid.
Its structure is mainly composed of valve body, solenoid, slide valve and reset spring. In the case of not energized by the reset spring to keep in the middle position or initial position (except pulse valve). The thrust of the solenoid acts on the slide valve through the push rod and pushes it from the rest position to the operating position (terminal position), thereby changing the direction of the liquid flow P→A and B→T or P→B and A→T. When the solenoid is de-energized, the slide valve is pushed back to its original rest position by the reset spring. When the solenoid is de-energized, the slide valve is pushed to move with the fault check button.
