Valves Option

The counterbalance valve protects rotation in the event of a hydraulic line failure and protect the actuator against excessive torque loading.
Hydraulic Schematic of Optional Counterbalance Valve
The counterbalance valve is optional on-demand. SUN brands or other top brands are available for different requests.

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. See specification pages for valve location.

The pilot ratio is 3:1. The valves are set to relieve at 3300 psi ± 300 psi (228 bar ±21 bar).

Mounting Type

Application

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, etc.
