Application
Construction Equipment
Load-holding and pressure protection for booms, outriggers, and high-inertia work functions.
Circuit context
How the valves are used
Construction hydraulics move heavy, overrunning loads. Counterbalance and relief cartridges are specified to keep motion controlled when gravity assists the actuator.
Typical challenges
- 01Overrunning and over-center loads
- 02Peak pressure spikes
- 03Rugged outdoor service
Engineering response
- 01Counterbalance valves matched to cylinder ratios
- 02Relief protection at 350 bar class
- 03Hardened internals for abrasive duty
