Design and Construction

Premium Material Selection: This balance valve is crafted from top-quality materials that exhibit outstanding mechanical characteristics. The valve body is usually constructed from high-strength alloys, which not only possess excellent resistance to high pressures but also are highly resistant to corrosion. This enables the valve to endure the tough working conditions typically encountered in construction sites and maintain its integrity over an extended period, thus ensuring a long service life.

Precision Machining and Design: The internal structure of the 013.439.105.OB balance valve is engineered with meticulous precision. The spool and the various ports are fabricated with high accuracy through advanced machining techniques. This precise design allows for seamless and smooth operation of the valve, ensuring that the spool can move effortlessly within the valve body. As a result, it minimizes energy losses due to friction and enables precise control over the flow of hydraulic fluid.

Working Principle

Flow and Pressure Regulation: The primary function of the balance valve 013.439.105.OB is to regulate the flow and pressure of hydraulic fluid within the system. It acts as a key element in maintaining an appropriate equilibrium between different hydraulic circuits. By carefully controlling the fluid flow, it prevents any significant imbalances in pressure that could otherwise lead to erratic operation or potential damage to other components of the concrete pump truck. For instance, it plays a crucial role in coordinating the extension and retraction speeds of hydraulic actuators like cylinders, ensuring that these movements are smooth and consistent.

Load-Holding Capability: Another essential aspect of its operation is its load-holding function. When the hydraulic system is in a stationary state or during intermittent breaks in operation, this balance valve effectively locks the hydraulic fluid in position. This prevents any unintended movement or drifting of the load, which could be caused by factors such as gravity or external forces. This function is of utmost importance for maintaining the stability and safety of the working parts of the concrete pump truck, including the boom and the outriggers.
