Komatsu PC35MR-2 20T-62-71160 Excavator Hydraulic Main Control Valve
The excavator control valve, also known as the main control valve (MCV), is a critical component in hydraulic systems of excavators and other heavy construction machinery. It regulates the flow, pressure, and direction of hydraulic oil to various actuators (such as hydraulic cylinders and motors), enabling precise control of movements like digging, lifting, swinging, and traveling.
Modern excavators rely on advanced hydraulic control valves to ensure smooth operation, energy efficiency, and safety. This guide explores the working principles, construction, functions, applications, maintenance, and future trends of excavator control valves.

The control valve operates based on hydraulic or electro-hydraulic signals from the operator’s joystick or control system. Its primary function is to direct pressurized oil to different actuators while maintaining optimal pressure and flow.
Directional Control: The valve shifts its internal spool to open or close oil passages, directing flow to the desired actuator.
Pressure Regulation: Relief valves and pressure compensators maintain system stability, preventing overload.
Flow Control: Adjusts oil flow rate to ensure smooth and proportional movement of hydraulic cylinders and motors.
Most modern excavators use load-sensing control valves, which adjust pump output based on demand, improving fuel efficiency.
