4WE10H3X/CG24N9K4 Electromagnetic Directional Valve H-Type for Zoomlion Concrete Pump Truck 6.1kg

Product Description

Design and Structure

Valve Body Structure: The valve body of the 4WE10H3X/CG24N9K4 is made of high-quality alloy steel, which has high strength and wear resistance, and can withstand the high pressure and impact of the hydraulic system in the concrete pump truck. Its structure is compact and reasonable, which is convenient for installation and connection in the hydraulic system.

Electromagnetic Actuator: It is equipped with a high-performance electromagnetic actuator, which can quickly and accurately control the movement of the valve spool. The electromagnetic actuator uses a DC 24V power supply (CG24 in the model), which has strong anti-interference ability and stable performance. The "N9K4" part in the model indicates the specific characteristics of the solenoid coil, such as its insulation class and protection level.

Sealing System: The valve is equipped with a high-quality sealing system to ensure reliable sealing performance. The seals are made of special materials that have excellent resistance to oil, wear and aging, effectively preventing hydraulic oil leakage and ensuring the normal operation of the hydraulic system.

Working Principle

Electromagnetic Control: When the electromagnetic coil is energized, it generates a magnetic field, which attracts the armature and drives the valve spool to move. According to the different energization states of the electromagnetic coil, the valve spool can be switched to different positions, thereby realizing the switching of the hydraulic oil flow direction in the valve.

Flow Control: In the H type function, when the valve spool is in the neutral position, all ports (P, A, B, T) are interconnected, allowing the hydraulic oil to flow freely between each port. This provides a special flow path for the hydraulic system, which can be used to achieve functions such as system unloading and oil return. When the valve spool is shifted to other positions by the electromagnetic actuator, the flow direction of the hydraulic oil between the ports P, A, B and T will change, so as to control the movement direction and speed of the hydraulic cylinder or hydraulic motor in the concrete pump truck's hydraulic system.

Performance Features

High Response Speed: Thanks to the advanced design of the electromagnetic actuator and valve spool structure, the 4WE10H3X/CG24N9K4 solenoid directional control valve has a very high response speed. It can quickly switch the flow direction of the hydraulic oil, enabling the concrete pump truck's hydraulic system to quickly respond to the operator's control commands and improve the working efficiency and accuracy of the equipment.

High Pressure Resistance: It is designed to withstand high hydraulic pressures, typically up to a certain rated pressure. This allows it to work stably in the high-pressure hydraulic system of the concrete pump truck without leakage or damage, ensuring the reliability and safety of the entire hydraulic system.

Good Flow Capacity: With a nominal size of 10, the valve has a relatively large flow passage area, which can provide a large enough flow capacity to meet the requirements of the concrete pump truck's hydraulic system for high-flow hydraulic oil. This ensures that the hydraulic components in the system can obtain sufficient hydraulic oil supply and work smoothly.

Low Power Consumption: The electromagnetic actuator of the valve is designed with energy-saving considerations and has relatively low power consumption. This not only helps to reduce the energy consumption of the concrete pump truck's electrical system but also helps to prolong the service life of the battery and other power supply equipment.
