Product Description
Sun Hydraulics CBCA-LHN Counterbalance Valve
The Sun Hydraulics CBCA-LHN is a pilot-assisted, poppet-type, screw-in hydraulic cartridge valve designed for reliable load-holding and motion control. It is intended to control an overrunning load by preventing it from running ahead of the pump. The valve provides a built-in check valve for free flow from the directional valve to the load, while the pilot-assisted relief valve controls flow from the load back to the directional valve. This configuration ensures smooth, stable, and chatter-free operation, making it ideal for applications requiring precise load control and safety against hydraulic line failure.
