Sun’s Load Adaptive counterbalance valves are designed to provide both stability and energy efficiency in a single-valve solution. Load Adaptive counterbalance valves may be used in place of a standard counterbalance valve in nearly any application. However, not all applications can take advantage of the Load Adaptive functionality, in which case the valve will be less economical than standard counterbalance valves.

Sun recommends considering the use of Load Adaptive valves when these situations exist:

• Overrunning or gravity-assisted loads
• When energy and fuel efficiency are important
• Where stable load control is important
• Where the machine lift-lower-lift duty cycle against gravity is repetitive and regular
• Where load pressures range from 500-4000 psi (35-280 bar)
• For pilot pressures less than ~2000 psi (140 bar)
