Design and Structure

High-Quality Materials: The valve body is made of high-strength alloy steel, which provides excellent resistance to wear, corrosion, and high-pressure conditions. This ensures the valve can withstand the harsh environment and heavy workloads in construction sites, guaranteeing a long service life.

Compact Design: It features a compact and modular structure, which not only saves space but also facilitates installation and maintenance. The integrated design of various components improves the overall reliability and stability of the valve, reducing the possibility of leakage and malfunctions.

Precision Engineering: The internal components, such as the spool and seat, are manufactured with high precision. The precise machining ensures a perfect fit between components, allowing for smooth operation and accurate control of fluid flow.

Working Principle

Flow Regulation: The LHDV 33P - 15 - M6 - 400/440 balance valve is primarily used to regulate the flow of hydraulic oil in the concrete pump truck's hydraulic system. It can precisely adjust the flow rate according to the actual working conditions of the pump truck. For example, when the pump truck is extending or retracting the boom, the valve will adjust the flow of hydraulic oil to ensure the boom moves smoothly and at the desired speed.

Pressure Balance: The valve is equipped with a pressure sensing and control mechanism. It continuously monitors the pressure in the hydraulic system and automatically adjusts to maintain a balanced pressure state. This helps to prevent pressure fluctuations and surges, which could otherwise cause damage to the hydraulic components and affect the performance of the pump truck.
