Leak-Free Load-Control Valve series BBV 6
Pressure [bar]
420
Flow rate [L/min]
50
Load-control valves in this series prevent hydraulic actuators from running ahead of the available oil supply. In one valve, they combine the functions of load-holding, safety and pipe-rupture protection. These hydraulic load-control valves from the series BBV 6… are pilot operated as well as high performance valves of size 6 and available as flange and piping valves. They are ideally suited for use in highpressure applications up to 420 bar (6000 psi). Thanks to the various pilot control variants, the cartridge can be optimally adapted to the system requirements.
- Two-stage load-control valve and bypass check valve are functionally combined in one coaxial valve assembly
- Leak-free load holding
- The load pressure has very little influence on the pilot pressure required → area ratio 1:66
- Guaranteed closing force for the load-control assembly → reliable shut-off even with a broken spring
- Thanks to the various pilot control styles, the valve can always be adapted to the system requirements
- Hardened, ground and lapped seat valve components ensure permanent leaktightness and long service life
- Optionally with pilot operated secondary pressure relief valve
- All external parts with zinc-nickel coating according to DIN EN ISO 19598
