Zoomlion Concrete Pump Truck Accessories Electromagnetic Directional Valve 4WE6Y70/HG24N9K4 (R901089243) 4WE6Y7X/HG24N9K4

Product Description

Design and Structure

Valve Body Material: Made of high-strength alloy steel, the valve body has excellent strength and wear resistance. It can withstand the high pressure and frequent impacts in the concrete pump truck's hydraulic system.

Electromagnetic Actuator: It is equipped with a high-performance electromagnetic actuator that can accurately and quickly control the movement of the valve spool. Operating on a DC 24V power supply (HG24), it has strong anti-interference ability and stable performance. The "N9K4" of the code represents the specific characteristics of the solenoid coil, such as insulation class and protection level.

Sealing System: The valve uses a high-quality sealing system made of special materials that are oil-resistant, wear-resistant, and aging-resistant. This ensures reliable sealing, preventing hydraulic oil leakage and guaranteeing the normal operation of the hydraulic system.

Working Principle

Electromagnetic Control: When the electromagnetic coil is energized, it generates a magnetic field that attracts the armature, driving the valve spool to move. Depending on the energization state of the electromagnetic coil, the valve spool can be switched to different positions, thus changing the flow direction of the hydraulic oil in the valve.

Flow Characteristics in Type Y: In the Y type configuration, when the valve spool is in the neutral position, the relationship between the ports is such that it allows for a specific flow path design. This can be used for functions like facilitating certain hydraulic operations or system balancing. When the valve spool is actuated by the electromagnetic force, the flow direction of the hydraulic oil among ports P, A, B, and T changes, controlling the movement direction and speed of hydraulic components in the concrete pump truck's hydraulic system.

Performance Features

Quick Response: The solenoid directional control valve 4WE6Y70/HG24N9K4 has a rapid response speed. It can quickly switch the flow direction of the hydraulic oil, enabling the concrete pump truck's hydraulic system to respond promptly to operator commands, improving the equipment's working efficiency and accuracy.

High Pressure Resistance: It is designed to withstand high hydraulic pressures, meeting the requirements of the high-pressure hydraulic system in the concrete pump truck. It can operate stably without leakage or damage under high-pressure conditions, ensuring the reliability and safety of the entire hydraulic system.

Optimal Flow Capacity: With a nominal size of 6, the valve has an appropriate flow passage area to provide sufficient flow capacity. This ensures that the hydraulic components in the system can receive an adequate supply of hydraulic oil, enabling them to operate smoothly.

Low Power Consumption: The electromagnetic actuator is designed with energy-saving in mind, consuming relatively low power. This helps reduce the energy consumption of the concrete pump truck's electrical system and extends the service life of the battery and other power supply equipment.
