The SUN CVGV-XCN is a high-performance, pilot-operated, balanced counterbalance valve designed for controlling overrunning loads. It allows free flow from the directional valve to the load (port 2 to port 1) while blocking flow in the opposite direction. A pilot signal allows the valve to open proportionally, providing smooth and controlled motion when lowering a load. This valve also offers thermal relief functionality, protecting the circuit from pressure spikes caused by thermal expansion. Its robust, cartridge-style design ensures reliable load-holding and safety in demanding hydraulic systems.
