Product Advantages

Hydraulic Motors: High torque output, High power density, Low Internal Leakage, Quiet Operation & Imported Sealing. Equipped with imported seals, it significantly bolsters the sealing effect, preventing hydraulic oil leakage and extending the service life of the motor.

High torque output

The hydraulic motor can provide extremely high starting torque at low speeds, making it particularly suitable for heavy-load or high-resistance scenarios

High power density

Compared with electric motors, hydraulic motors are smaller in size and lighter in weight, yet they can output greater power, making them suitable for space-constrained applications.

Exceptional Internal Leakage Control

The product features minimal internal leakage, effectively reducing hydraulic oil loss. This not only enhances the stability of the system but also optimizes energy utilization.

Low Noise Operation

During operation, it generates minimal noise, creating a quieter working environment. It is particularly suitable for noise - sensitive applications.

Superior Sealing Performance

Equipped with imported seals, it significantly bolsters the sealing effect, preventing hydraulic oil leakage and extending the service life of the motor.

Support Hydraulic Valve Types

ChangJia stands as the preeminent provider in industrial hydraulics, boasting the globe's most extensive collection of premium hydraulic valves. With our hydraulic valves at your disposal, you gain precise command over volume flow regulation.

Pressure Valves

The pressure valve can automatically open or close according to the set pressure value, so as to maintain the pressure in the system within a safe range. When the system pressure exceeds the set value, the pressure valve will automatically open to release excess pressure and prevent equipment damage due to over pressure; When the pressure is lower than the set value, the pressure valve will close to maintain the normal operation of the system.

Directional Valves

Directional valves serve as pivotal components that dictate the flow direction within a hydraulic system. By precisely managing this flow, they directly govern the movement or rotational orientation of hydraulic actuators, ensuring seamless operation and accurate positioning.

Flow Valves

Flow valves play a critical role in controlling the volume flow rate of hydraulic fluid. Through this regulation, they effectively determine the speed at which hydraulic actuators operate, enabling precise control over the motion and performance of various hydraulic-powered machinery and equipment.

Proportional Valves

A proportional valve is a control component that precisely regulates the flow rate, pressure and direction of a fluid through electrical signals. Maintain the stability of the system pressure by changing the resistance at the valve port or directly adjusting the pressure feedback loop. Proportional valves have become core components in industrial automation, precision machinery and energy-saving systems, promoting the development of equipment towards intelligence and efficiency.

Cartridge Valves

Cartridge valves are key components widely used in hydraulic systems, mainly for direction control, pressure control, flow control, and logic control of compound functions.The cartridge valve precisely controls the main oil circuit by controlling the oil pressure to drive the movement of the valve core, and by combining the area ratio and the balance relationship of the spring force. Its modular, high-flow and flexible features make it an ideal choice for complex hydraulic systems

ChangJia piston pumps present a versatile array of capabilities, catering to both open-and closed-circuit systems in medium-to heavy-duty industrial scenarios. The fixed-displacement variants boast outstanding volumetric and mechanical efficiencies. Meanwhile, the variable - displacement models afford you the flexibility to select control options, precisely aligning with specific pressure and flow requirements.

Hydraulic Steering Units

ChangJia hydraulic steering unit is a critical component in agricultural machinery, enabling precise control of direction through pressurized hydraulic fluid. It converts mechanical input from the steering wheel into hydraulic force, reducing manual effort and providing smooth, responsive maneuverability. This system is widely used in agricultural machinery due to its reliability, durability, and ability to handle high loads. Hydraulic steering ensures safety and efficiency, even in demanding conditions, by delivering consistent performance and reducing operator fatigue.
