Sun Counterbalance Valve

Sun counterbalance valves are precision hydraulic components designed to safely control overrunning or suspended loads. They maintain stable pressure, prevent load drift, and ensure smooth, controlled motion in lifting and holding applications. Widely used in construction equipment, cranes, material-handling systems, and industrial machinery, Sun counterbalance valves offer reliable load-holding performance, excellent pressure stability, and long service life. Their compact cartridge design allows easy installation into manifolds, reducing system size while improving safety, operational efficiency, and overall hydraulic system reliability.
