Use counterbalance valves to restrain flow to keep a load from running ahead of the pump, preventing cavitation. They serve as safety devices in case of line breakage, provide thermal protection with open center valves, and can function as deceleration valves with the circuit shown in the data sheet.

Pilot to open check valves will positively lock the load in position, but will release the load upon application of pressure to the opposite port which is cross piloted. Do not use if overhauling conditions exist.
