What is the pressure setting of a counterbalance valve?

The pressure setting of a counterbalance valve is typically set just above the load pressure but below the load plus the system pressure. This setting is crucial for the valve to maintain control over the load and prevent uncontrolled movement. When the pressure in the system exceeds this setting—such as during a lift or lowering of a load—the valve will open to allow fluid to pass through, thus preventing potential system overload and ensuring stability.

Setting the counterbalance valve in this manner allows it to effectively manage the load, maintaining it in place without allowing it to drop uncontrollably due to gravity or other forces. This strategic placement is essential for proper function and safety in hydraulic systems, especially in applications where loads can shift unexpectedly.
