Load Control Valves BBV

Description

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.

Advantages

  • 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 (only for housing design)
