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.
