Load Control Valves BBV

Description

Load control valves of this type prevent a hydraulic actuator from running ahead of, or "over-running", the available oil supply. They simultaneously act as a control-, load-holding-, safety- and pipe-rupture valve.

Advantages

- Load control valve with pre-opening
- Load pressure acts in the closing direction; valve closes even with broken spring
- Leak-free valve seats; hardened, ground and lapped
- Pilot pressure is almost independent of load pressure (1:66)
- Pilot pressure can be matched to the system
- Body-mounted valves can have an integral two-stage secondary pressure relief valve
