Counter Balance Cartridge Valve CBCG-LKN 77722547 77722548 for Sun Hydraulics

Counter Balance Cartridge Valve CBCG-LKN for Sun Hydraulics

This counter balance cartridge valve, cross-referenced as 77722547 and 77722548, meets Sun Hydraulics cavity standards to control overrunning loads in hydraulic circuits.

Overview

The counter balance cartridge valve CBCG-LKN is a pilot-assisted, poppet-type valve that provides load holding and motion control for hydraulic actuators. It prevents runaway loads in lifting applications such as forklifts, telehandlers, and man lifts. This replacement cartridge works in Sun Hydraulics standard cavities and is rated for flows up to 15 GPM.

Built For Performance

• Pilot-assist opening reduces pressure spikes during load lowering
• Hardened steel poppet resists contamination wear
• Adjustable relief setting allows fine‑tuning of load‑holding pressure
• Reverse flow check function enables free lift when pilot pressure is applied
• Corrosion‑resistant zinc‑nickel plating extends service life in harsh environments

On-The-Job Use

• In hydraulic circuits for boom and arm cylinders on compact excavators
• On outrigger stabilizers to prevent vehicle settling under load
• In scissor‑lift platforms to control descent speed
• On telehandler fork carriages for safe load handling

Specs At A Glance

Good To Know

Q: What pilot ratio does this CBCG-LKN valve use? A: The standard CBCG-LKN is a 3:1 pilot ratio; verify your circuit's pilot pressure requirements before installation.

Q: Can I use this valve in a single-acting cylinder application? A: Yes, but you must ensure the pilot port is properly connected to the cylinder cap end; the valve will block flow in the opposite direction until pilot pressure is applied.

Slight variation in finish or dimensions may occur between production runs, and serial number can affect fitment, so confirm compatibility before ordering.
