Working Principle
When the operator steps on the pedal of this foot valve, the internal spool moves to change the direction of hydraulic oil. Pressurized oil inside the hydraulic system is distributed to corresponding hydraulic cylinders and hydraulic motors, to realize lifting, digging, slewing actions of the excavator Machine. Return spring resets the spool once releasing the pedal, cutting off oil supply and stopping equipment movement.
