Atmospherically vented counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. Backpressure at port 2 does not affect the valve setting because the spring chamber is atmospherically referenced.

Main Applications
Check function: CACG-LGN cartridge valves are mainly used to realize the check function of the hydraulic system, to ensure that the fluid can only flow in one direction, to prevent the system instability caused by backflow.
Remote pressure regulation and multi-stage pressure control: these valves are small in size, fast in response, stable in pressure, and very suitable for applications requiring remote pressure regulation and multi-stage pressure control.

Characteristic description
Small size and fast response: The design of the CACG-LGN cartridge valve allows for a small size and fast response for space-constrained applications.
Stable pressure: The valve is able to maintain a stable pressure output, ensuring the continuity and reliability of the hydraulic system.
Applicable media: suitable for hydraulic and pressure regulating systems, the operating oil temperature range is -17 ~ 70 ℃, the oil cleanliness requirements for NAS11 class, need to use 25um or more precise filter
