The balance valve with the code 07188021000000B is a specialized
component designed for Zoomlion concrete pump trucks, particularly
those equipped with the CIFA 41-meter configuration. It plays a
critical role in the proper functioning and performance of the
hydraulic system of these pump trucks.
High-Quality Materials: This balance valve is fabricated using top-notch materials that
possess excellent mechanical properties. The body of the valve is
typically made from robust alloys, which are able to withstand high
hydraulic pressures without deformation. Moreover, these materials
have good corrosion resistance, ensuring that the valve can endure
the harsh working environments often encountered in construction
sites, such as exposure to dust, moisture, and chemicals, and
maintain its structural integrity over a long period.
Precision Engineering: The internal structure of the balance valve is engineered with a
high level of precision. The components like the spool and the
ports are carefully machined to exacting tolerances. This precise
design allows for smooth and accurate operation of the valve. The
spool can move precisely within the valve body, enabling precise
control over the flow of hydraulic fluid while minimizing friction
and energy losses during the operation of the hydraulic system.
Flow and Pressure Regulation: The main function of this balance valve is to regulate the flow and
pressure of the hydraulic fluid within the system. In the context
of the CIFA 41-meter concrete pump truck, it is crucial for
maintaining a proper balance between different hydraulic circuits.
For example, when the boom is being extended or retracted, it
ensures that the flow of hydraulic fluid to the relevant actuators
is controlled in a way that the movement is smooth and stable. It
prevents sudden pressure surges or imbalances that could lead to
jerky movements or even damage to the boom structure or other
hydraulic components.
Load-Holding Function: Another significant aspect of its operation is its load-holding
capability. When the pump truck is in a stationary state, perhaps
during a pause in the concrete pumping process or when the boom is
positioned at a certain angle, the balance valve effectively locks
the hydraulic fluid in place. This prevents the load, such as the
weight of the boom and the attached concrete delivery pipe, from
drifting or moving due to gravity or other external forces. This
ensures the safety and stability of the entire pumping setup.
