The balance valve with the code 07188021000000B is a specialized component designed for Zoomlion concrete pump trucks, particularly those equipped with the CIFA 41-meter configuration. It plays a critical role in the proper functioning and performance of the hydraulic system of these pump trucks.
High-Quality Materials: This balance valve is fabricated using top-notch materials that possess excellent mechanical properties. The body of the valve is typically made from robust alloys, which are able to withstand high hydraulic pressures without deformation. Moreover, these materials have good corrosion resistance, ensuring that the valve can endure the harsh working environments often encountered in construction sites, such as exposure to dust, moisture, and chemicals, and maintain its structural integrity over a long period.
Precision Engineering: The internal structure of the balance valve is engineered with a high level of precision. The components like the spool and the ports are carefully machined to exacting tolerances. This precise design allows for smooth and accurate operation of the valve. The spool can move precisely within the valve body, enabling precise control over the flow of hydraulic fluid while minimizing friction and energy losses during the operation of the hydraulic system.
Flow and Pressure Regulation: The main function of this balance valve is to regulate the flow and pressure of the hydraulic fluid within the system. In the context of the CIFA 41-meter concrete pump truck, it is crucial for maintaining a proper balance between different hydraulic circuits. For example, when the boom is being extended or retracted, it ensures that the flow of hydraulic fluid to the relevant actuators is controlled in a way that the movement is smooth and stable. It prevents sudden pressure surges or imbalances that could lead to jerky movements or even damage to the boom structure or other hydraulic components.
Load-Holding Function: Another significant aspect of its operation is its load-holding capability. When the pump truck is in a stationary state, perhaps during a pause in the concrete pumping process or when the boom is positioned at a certain angle, the balance valve effectively locks the hydraulic fluid in place. This prevents the load, such as the weight of the boom and the attached concrete delivery pipe, from drifting or moving due to gravity or other external forces. This ensures the safety and stability of the entire pumping setup.
