Safety & Protection
The counterbalance valve protects rotation in the event of a hydraulic line failure and protects the actuator against excessive torque loading. The hydraulic schematic of the optional counterbalance valve ensures operational stability. These valves are optional on-demand, with top brands available for different technical requirements.
Manufactured from aluminum, the valve blocks are bolted to a flat mounting pad on the actuator housing. Three bolts secure the valve block to the actuator. The pilot ratio is 3:1. The valves are set to relieve at 3300 psi ± 300 psi (228 bar ± 21 bar).
Common Applications
Steering
Boom positioning
Drill positioning
Platform/basket/jib rotation
Conveyor positioning
Davit rotation
Mast/hatch positioning
Access ramp deploy
Attachment rotation
Shotcrete nozzle rotation
Pipe handling
Brush positioning
