Single Overcenter Valve 60L/Min Hydraulic Counterbalance Valve Supplier
When a hydraulic system uses single-acting cylinders, it requires a way to control the flow of fluid in one direction while allowing free flow in the opposite direction. This is where single balance valves come into play.
The primary function of a single balance valve is load holding. By preventing backflow when pressure exceeds set limits, it ensures that loads are securely held in position without any drift or unintended movement. This feature makes it suitable for applications that require precise positioning and stability, such as cranes, lifts, and presses.
Single balance valves can be adjusted to specific pressure settings based on system requirements through their pilot-operated relief valves. This allows for customization according to different loads and operating conditions.
In summary, single balance valves are crucial components that provide precise control over movements within hydraulic systems using single-acting cylinders. They enable load holding capabilities while ensuring safe operation by preventing backflow under excessive pressures.

Working Principle:The operational principle of a single balance valve revolves around maintaining a harmonious flow of fluid to and from the single-acting hydraulic cylinder.
Here's a closer look at how it typically functions:
Controlled Flow |
The valve regulates the flow of hydraulic fluid to the single-acting cylinder. It allows fluid to flow freely from the hydraulic pump to extend the cylinder but regulates the flow during the cylinder's retraction phase. |
Load-Holding |
During the cylinder's retraction or lowering phase, the valve creates a controlled resistance to fluid flow, which prevents the load from dropping too quickly. This load-holding capability ensures safety and stability in applications where precise control is necessary. |
Balanced Flow |
The valve maintains a balanced flow of fluid to and from the cylinder, ensuring smooth and controlled operation without sudden movements or jerks. |
