Hitachi EX200-5 Control Valve 4366959 Hydraulic Distributor

Hyundai EX200-5 4366959 control valve Hydraulic distributor for excavator parts

The control valve (also known as the main control valve or multi-valve block) is the central hydraulic control component in excavators. It consists of multiple parallel spools that precisely distribute high-pressure oil from the pump to actuators (e.g., hydraulic cylinders, motors) based on operational demands, enabling coordinated machine movements.

Working Principle

1. Flow Distribution:
   Operator joystick or electronic signals shift valve spools, adjusting port openings to control oil flow rate and direction to each actuator.

2. Pressure Regulation:
   Integrated pressure compensators and overload relief valves maintain stable flow under varying loads while preventing pressure spikes.

3. Multi-circuit Coordination:
   Parallel spool design allows simultaneous operation of multiple actuators (e.g., boom lifting + arm retraction), with the system automatically splitting pump flow.
