Zoomlion Concrete Pump Hydraulic Directional Valve 4WH22E7X 1010301152

Ürün Açıklaması

The Hydraulic directional valve, with the model number 4WH22E7X and part code 1010301152, in a concrete pump truck serves a crucial function in controlling the flow and direction of hydraulic fluid within the hydraulic system.

The primary role of the Hydraulic directional valve is to regulate the flow of hydraulic fluid to different hydraulic components and actuators within the concrete pump truck. It determines the direction of fluid flow based on the position of its internal spool or valve element.

The valve operates through hydraulic pressure and mechanical forces. By manipulating the position of the spool, the valve can open or close different passages, allowing hydraulic fluid to flow in the desired direction and control the movement of hydraulic cylinders or motors.

By controlling the flow and direction of hydraulic fluid, the Hydraulic directional valve enables various functions within the concrete pump truck. For example, it can control the extension and retraction of hydraulic cylinders, the rotation of the boom, or the operation of other hydraulic actuators.

Moreover, the Hydraulic directional valve contributes to the overall efficiency and safety of the concrete pump truck. It allows for precise control over hydraulic movements, ensuring smooth and accurate operation. It also provides the ability to quickly and reliably reverse hydraulic flow, facilitating rapid response and emergency shutdown if necessary.

Additionally, the Hydraulic directional valve helps protect the hydraulic system by preventing fluid backflow and maintaining the integrity of the hydraulic circuits. It helps regulate pressure and prevent damage to the hydraulic components.
