Zoomlion Concrete Pump Truck Accessories Electromagnetic Directional Valve SDHE-0713-X24DC (Y-shaped)

Product Description

Design and Structure

Valve Body: Constructed from high-strength, corrosion-resistant materials, usually a special alloy, the valve body is designed to endure the high pressures and harsh working conditions in the hydraulic system of a concrete pump truck. Its robust and durable structure ensures long-term reliability and stability, even under continuous heavy-duty usage.

Electromagnetic Actuator: Equipped with a high-performance electromagnetic actuator, this valve can precisely control the movement of the spool. The actuator is designed to respond quickly and accurately to electrical signals, converting electrical energy into mechanical force. It has excellent heat dissipation and electromagnetic shielding properties to resist interference, ensuring stable operation in various electromagnetic environments.

Sealing System: The valve is equipped with a high-quality sealing system made of advanced rubber and polymer materials. These seals effectively prevent hydraulic fluid leakage under high pressure and frequent operation, ensuring the efficiency and performance of the valve. They are highly resistant to wear, aging, and the chemical effects of the hydraulic fluid, prolonging the service life of the valve.

Working Principle

Electromagnetic Control: When a 24V direct current is applied to the electromagnetic coil of the actuator, a strong magnetic field is generated. This magnetic field attracts the armature, which is connected to the valve spool, causing the spool to move within the valve body. By controlling the on/off state and the magnitude of the current, the position of the spool can be accurately adjusted to achieve the desired control of the hydraulic fluid flow.

Flow Regulation: In the case of the Y-type spool, the valve has specific flow characteristics. Depending on the position of the spool, it can connect or disconnect different ports, allowing the hydraulic fluid to flow in different directions and control the operation of various components in the concrete pump truck's hydraulic system. For example, it can direct the fluid to extend or retract the boom cylinders, control the rotation of the mixer, or adjust the position of the chute.

Performance Features

High Pressure Resistance: The SDHE-0713-X24DC (Y Type) is designed to withstand high hydraulic pressures commonly encountered in concrete pump truck operations. It can operate stably at pressures required for pumping concrete and performing other heavy-duty tasks, providing reliable power for the hydraulic system.

Precise Flow Control: With its advanced design and high manufacturing precision, this valve offers excellent flow control capabilities. It can accurately adjust the flow rate and direction of the hydraulic fluid, ensuring smooth and precise operation of the pump truck's hydraulic components. This precision is crucial for the accurate positioning and movement of the boom, chute, and other parts, enabling efficient and accurate concrete placement.

Rapid Response: The valve has a short response time, allowing for quick changes in the direction and flow of the hydraulic fluid. This rapid response is essential for the efficient operation of the concrete pump truck, enabling it to quickly adapt to different working conditions and operator commands, improving the overall operational efficiency and productivity.

Low Leakage: Thanks to its reliable sealing system, the SDHE-0713-X24DC (Y Type) has a very low leakage rate. This helps to maintain the efficiency of the hydraulic system by minimizing energy loss due to leakage and ensuring that the hydraulic power is effectively transmitted to the actuators, thereby improving the overall energy efficiency of the pump truck.
