Who We Are

Work To Drive Innovation Of Core Hydraulic Components

Remain true to our original aspiration and keep our mission firmly in mind

Everything will be built around long-term value, and the long-termism way of thinking is both a prerequisite and a consequence of actually owning something.

ChangJia is a leading international hydraulic technology enterprise integrating R&D, manufacturing, sales, and services. Specializing in the innovation and production of core hydraulic components, our product portfolio encompasses a full range of high-end hydraulic components, including hydraulic piston pumps, piston motors, orbital  motors, hydraulic valves, gear pumps, and solenoid valves.


Guided by the "zero - defect" quality management philosophy, our products are widely applied in fields such as construction machinery, agricultural machinery, sanitation vehicle, winning high acclaim from global customers.

Three Main Business

In collaboration with multiple universities, we have established joint laboratories, fostering a closed-loop innovation ecosystem that seamlessly integrates technological research, process transformation, and market application. Annually, we roll out dozens of new hydraulic products while continuously expanding our portfolio of technical patents. Our leadership in cutting-edge fields such as high-pressure energy efficiency and intelligent control is driving transformative advancements across the industry.
Hydraulic Valve
As the core control element of the hydraulic system, it adjusts the oil flow direction, pressure and flow rate through the displacement of the valve core to accurately control the movement of the equipment. It is main divided into five categories: directional valve, pressure valve , flow valve, proportional valves and cartridge valves. It is widely used in mechanical power switching and precision systems to ensure efficient operation.
Hydraulic Pump
As the power heart of the hydraulic system, it converts mechanical energy into hydraulic energy and continuously outputs high-pressure oil to drive the actuator. The core types include gear pumps, piston pumps and vane pumps, which support the stable operation of engineering machinery, agricultural machinery and ship systems with high efficiency, pressure resistance and strong adaptability.
Hydraulic Motor
Compact structure, large torque, high pressure resistance, suitable for rotary drives such as engineering machinery and agricultural equipment,etc. taking into account both high efficiency and durability.
