Leak-Free Load-Control Cartridge Valve series BBV-C
Pressure [bar]
420
Flow rate [L/min]
50
Leak-Free 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 loadholding, safety and pipe-rupture protection. These hydraulic load-control cartridge valves from the series BBV 6 C-… are size 6, pilot operated, high performance screw-in cartridges with an M42x1.5 mounting thread. They are ideally suited for use in high-pressure applications up to 420 bar (6000 psi). Thanks to the various pilot control variants, the cartridge can be optimally adapted to the system requirements
- Compact design for cavity type according to Bucher standard – M42x1.5
- 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
- All external parts with zinc-nickel coating according to DIN EN ISO 19598
