Design and Structure

Premium Material Selection: The valve body is crafted from high-quality stainless steel, which provides exceptional resistance to corrosion and wear. This makes the valve highly durable and suitable for the harsh and demanding environments of construction sites, where it may be exposed to moisture, dust, and various chemicals.

Innovative Design: It features an innovative and streamlined structure. The design focuses on reducing fluid resistance and improving flow efficiency. The internal channels are carefully designed to ensure a smooth and stable flow of hydraulic oil, minimizing pressure losses and maximizing the overall performance of the valve.

High-Precision Manufacturing: The valve components, including the spool, valve seat, and springs, are manufactured with extremely high precision. The tight tolerances ensure accurate fit and reliable operation. The surface of the components is carefully treated to reduce friction and improve the responsiveness of the valve.

Working Principle

Flow Control: The LHDV 33BP - 15 - N6 - 400/440 balance valve is responsible for precisely controlling the flow of hydraulic oil in the concrete pump truck's hydraulic system. It can adjust the flow rate according to the specific requirements of different working conditions. For example, during the concrete pumping process, it ensures that the correct amount of hydraulic oil reaches the boom and other actuators, enabling smooth and accurate movements.

Pressure Equilibration: The valve is equipped with a sophisticated pressure sensing and control mechanism. It continuously monitors the pressure in the hydraulic system and automatically adjusts the valve opening and closing to maintain a balanced pressure state. This helps to prevent pressure spikes and fluctuations, which could potentially damage the hydraulic components and affect the overall performance of the pump truck.
