The Balance Valve LHDV 33P - 15 - L8 - 400/440 is an essential component within the array of Zoomlion concrete pump truck accessories. It plays a significant role in ensuring the optimal performance and smooth operation of these powerful construction machines.

Design and Construction

This balance valve showcases a meticulous design, engineered with precision to meet the demanding requirements of concrete pump truck applications. Its structure is both compact and sturdy, enabling it to fit snugly within the hydraulic systems of the pump trucks without occupying excessive space.

The valve is fabricated from high-quality materials, carefully selected for their excellent mechanical properties. The use of robust alloys ensures remarkable durability, allowing it to withstand the harsh operating conditions typically encountered at construction sites, including exposure to dust, vibrations, and fluctuating temperatures.

Working Principle

Operating on a sophisticated hydraulic principle, the LHDV 33P - 15 - L8 - 400/440 balance valve serves as a key regulator within the system. It constantly monitors the pressure differentials between various sections of the hydraulic circuit. When the pressure on one side of the valve approaches or exceeds the preset thresholds related to the 400/440 bar rating, it instantaneously adjusts the flow of hydraulic fluid.

By precisely controlling the fluid flow, it maintains a delicate balance of pressures, preventing sudden surges or drops that could otherwise disrupt the smooth operation of the concrete pump truck's hydraulic actuators, such as the boom and pumping mechanisms.
