Product Introduction

This main pump electromagnetic valve is a specialized core component for the hydraulic electronic control system of HD820, HD700, and HD1023 excavators. It is directly installed on the main hydraulic pump and is responsible for the critical tasks of regulating the flow and pressure of the hydraulic system.

It receives the electrical signals output by the excavator controller and precisely controls the opening and closing of the valve core through electromagnetic drive force. This enables the adjustment of the output displacement of the main pump, achieving the matching of the overall machine power and coordinating the force and speed of the excavation actions. If this electromagnetic valve experiences malfunctions such as jamming, coil burnout, or sluggish valve core response, the equipment is prone to serious problems such as insufficient excavation power, inconsistent movement speed, abnormal noise from the main pump, engine stall, and even complete paralysis of the machine's operations. This directly leads to construction site shutdown. The product strictly conforms to the installation dimensions, valve core stroke, coil electrical parameters, and oil port specifications of the original factory parts. It can be directly replaced with the faulty parts of the original vehicle without modifying the pipes and circuits. The disassembly and assembly are simple, enabling rapid repair of hydraulic control abnormalities and restoration of the machine's operational performance.
