Product Description

Sany Excavator Main Control Valve Drain Pin Cover for SY135 SY365 Distribution Valve Housing Assy

Essentially a proportional pilot hydraulic control valve, the excavator joystick outputs control‑purpose oil to drive the main multi‑way valve instead of directly powering excavator movements, thus regulating the speed and direction of machine actions. Located on the left and right within the operator cabin, the excavator control lever—pilot control lever, hydraulic lever or joystick—is the vital component for operators to command all excavator functions, serving as the machine’s “steering wheel and limbs”.

Operation Mode

All excavator movements are controlled by tilting the joystick in all directions:
  • Boom (main arm) lifting motion
  • Stick (secondary arm) extension and retraction
  • Bucket opening and closing operation
  • Left‑right upper‑structure slewing
  • Coordinated control with foot pedal valves for traveling

Working Principle

A hydraulic pilot valve is integrated inside each handle:
  • Pushing the handle shifts the internal spool
  • Low‑pressure hydraulic control signal is transmitted
  • Main hydraulic multi‑way valve is governed
  • Cylinders and motors execute actions with adjustable speed and direction

Proportional Speed Regulation

Greater handle deflection enlarges spool opening → increases pilot output pressure → expands main valve opening → speeds up boom, stick, bucket and slewing functions. Once the handle is released, return springs restore the handle and spool to neutral, disconnecting the pilot oil circuit, releasing pressure, resetting the main valve, and instantly ceasing all movements.
