Load Control Valves BBV

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.

• 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)
