Product Description

Excavator Spare Parts Hydraulic Valve Drain Screw Cover Pin DH300-7 DH225-9  Distribution Valve Drain Pin Cover

At its core, the excavator joystick is a proportional hydraulic pilot control valve. It outputs pilot control oil to activate the main multi‑way valve rather than directly driving excavator movements, determining the speed and direction of all machine actions. Mounted on the left and right of the operator cabin, the control lever (also called pilot control lever, hydraulic lever or joystick) is the key component for controlling every excavator function, acting as the machine’s “steering wheel and functional limbs”.

Operational Method

All excavator motions are commanded by moving the joystick in diverse directions:
  • Boom (main arm) elevation and lowering
  • Stick (secondary arm) extension and retraction
  • Bucket opening and closing cycles
  • Left‑right slewing of the upper machine body
  • Joint control with foot pedal valves for traveling

Operating Mechanism

An internal hydraulic pilot valve is housed in each handle:
  • Handle manipulation displaces the internal spool component
  • Low‑pressure hydraulic control signal is output
  • Main multi‑way hydraulic valve is actuated
  • Cylinders and motors perform directional, speed‑variable movements

Proportional Speed Modulation

Increased handle tilt expands spool opening → raises pilot pressure output → widens main valve opening → accelerates boom, stick, bucket and slewing operations. After releasing the handle, return springs reset the handle and spool to neutral, sealing the pilot oil path, releasing system pressure, resetting the main valve, and halting all movements immediately.
