Product Description

The hydraulic control core assembly suitable for 7-ton small excavators serves as the flow control center of the entire machine's hydraulic system. It receives the high-pressure oil from the main pump and regulates the pressure and flow for the boom, dipper, bucket, rotation, and traveling mechanisms. This directly determines the digging force of the equipment, the sensitivity of the action response, the coordination of compound actions, and the overall operation feel of the machine.

It is made by casting high-strength ductile iron in one piece. The overall structure of the valve body is compact and the rigidity is sufficient. It is suitable for the limited installation space of the small pump housing and can withstand the continuous vibration and pressure impact during construction operations. It reduces the risks of valve body deformation, internal oil passage cracking, and oil leakage. All core components such as the main valve core, overload relief valve, supplementary oil valve, pressure compensation valve, etc., are made of high wear-resistant alloy steel. They undergo quenching and tempering heat treatment, surface strengthening, and high-precision grinding processing. The clearance between the valve core and the valve hole is strictly in line with technical parameters, significantly reducing the probability of valve core scratching, impurities blocking, and abnormal increase in internal leakage.
