Design and Construction

High-Quality Materials: This balance valve is manufactured using premium materials that possess excellent mechanical properties. The body of the valve is typically made from high-strength alloys, which can endure high pressures and resist corrosion, ensuring its durability and long service life even in harsh working environments.

Precision Engineering: It features a precisely engineered internal structure. The spool and ports are machined with high precision to achieve accurate control of the hydraulic fluid flow. The design allows for smooth movement of the spool within the valve body, minimizing friction and energy losses during operation.

Working Principle

Flow and Pressure Control: The balance valve 013.439.105.OA functions to regulate the flow and pressure of hydraulic fluid in the system. It maintains a proper balance between different hydraulic circuits, preventing excessive pressure differences that could lead to unstable operation or damage to components. For example, it can ensure that the extending and retracting speeds of certain hydraulic actuators, such as cylinders, are controlled in a balanced manner, allowing for smooth and coordinated movements.

Load-Holding Function: One of its key functions is to provide load-holding capabilities. When the hydraulic system is in a static state or during a pause in operation, the balance valve can effectively lock the hydraulic fluid in place, preventing the load from drifting or moving unintentionally due to gravity or other external forces. This is crucial for maintaining the safety and stability of the concrete pump truck's working parts, such as the boom or outriggers.
