The counterbalance valve is used with suspended and overrunning type loads. Back pressure may adversely affect the operation of a standard non-vented counterbalance as it directly increases the valve setting, opposing pilot pressure. Hydra Part. The control creates a dynamic setting that is lower than the thermal relief setting but is never more than necessary to provide safe, reliable load control. depend on Sun Hydraulics to make our machines safer and more efficient. Two check valve cracking pressures are available. Flow Control Valves. CP441-1 Counterbalance Valve Twitter . Download a PDF about the Sun Counterbalance families.
