Hydraulic Pump Electromagnetic Valve EHPR98-T33-24ER Excavator Mechanical Parts

The main function of excavator solenoid valve is to control the direction, flow and speed of fluid, so as to realize accurate control of various actions of excavator. As the basic component of automation, solenoid valve belongs to the actuator, which can cooperate with different circuits to achieve the expected control, with high accuracy and flexibility.

Specifically, the excavator solenoid valve plays several key roles in the excavator:

Safety lock solenoid valve: When the lock lever is lowered, the safety lock solenoid valve is in the energized state, and the pilot oil circuit is connected after the solenoid valve is switched.
Rotary brake solenoid valve: when operating the rotary motion, the power is cut off, the valve core does not switch, and the pilot oil path reaches the brake piston through the rotating horse to release the brake.
Walking 1/2 speed electromagnetic valve: it controls the switching between 1 speed and 2 speed of walking speed.
Booster solenoid valve of working device: improve excavation strength
Unloading proportional valve: control the pressure oil that is not working in the hydraulic system to return to the hydraulic oil tank to eliminate the residual pressure of each actuator.
Proportional valve for walking straightness: keep walking straightness during compound action operation.
In addition, the solenoid valve can also cooperate with different circuits to achieve the expected control, ensuring the accuracy and flexibility of control.
