Zoomlion Concrete Pump Truck Accessories Electromagnetic Directional Valve DA6002CNJW (H-type)

Product Description

Design and Structure

Valve Body Material: Constructed from high-strength, corrosion-resistant alloy, the valve body is designed to withstand the demanding conditions of the concrete pump truck's hydraulic system. It can endure high pressures, abrasive fluids, and mechanical stresses, ensuring long-term reliability and performance.

Electromagnetic Actuator: Equipped with a powerful and efficient electromagnetic actuator, this valve can convert electrical energy into precise mechanical motion. The actuator is designed for quick response and high durability, capable of withstanding frequent switching operations without degradation in performance.

Sealing Mechanism: The valve features an advanced sealing system using high-quality sealing materials. These materials provide excellent resistance to oil, wear, and aging, effectively preventing leakage and maintaining the integrity of the hydraulic system. The sealing mechanism ensures that the valve operates with minimal fluid loss, even under high-pressure differentials.

Working Principle

Electromagnetic Control: When an electrical signal is applied to the electromagnetic coil, a magnetic field is generated. This magnetic field attracts the armature, which in turn moves the valve spool. By controlling the on/off state and magnitude of the electrical signal, the position of the valve spool can be precisely adjusted, thereby regulating the flow direction and path of the hydraulic fluid.

Flow Characteristics in Type H: In the H type configuration, when the valve is in the neutral position, all ports (P, A, B, and T) are interconnected. This allows for free flow of hydraulic fluid between all ports, which is useful in certain hydraulic system configurations where fluid needs to be circulated or relieved in a specific way. When the valve spool is actuated by the electromagnetic force, it changes the connection pattern of the ports, enabling the controlled flow of hydraulic fluid to drive the various components of the concrete pump truck's hydraulic system.

Performance Features

High Reliability: Engineered for maximum reliability, the DA6002CNJW solenoid directional control valve can operate continuously under harsh conditions with minimal risk of failure. It is designed to withstand a large number of switching cycles, ensuring stable performance over the long term and reducing the need for frequent maintenance and replacement.

Excellent Sealing Performance: With its superior sealing system, the valve exhibits extremely low leakage rates. This is crucial for maintaining the efficiency and accuracy of the hydraulic system, as it prevents fluid loss and ensures that the correct amount of pressure and flow is delivered to the intended components.

Wide Pressure Range: Capable of operating over a wide range of pressures, this valve is suitable for use in various concrete pump truck models and applications. Whether in low-pressure or high-pressure hydraulic systems, it can adapt and perform optimally, providing consistent control and operation.

Rapid Response: The valve is designed for fast response times, allowing for quick changes in the flow direction of the hydraulic fluid. This enables the concrete pump truck's hydraulic system to react promptly to operator commands, enhancing the overall operational efficiency and responsiveness of the equipment.
