Principle of operation

P2

P1

The VB020, VB0E0 and VB0F0 supply two operating pressures to the service brakes proportional to the pedal position: the pressure from the valve to the brakes increases, from zero when the pedal is released, to a preset pressure, as the pedal is fully depressed. Dual-circuit protection: in the event of failure due to contamination or hydraulic hose rupture in either circuit, the VB020, VB0E0, and VB0F0 design enables continued safe operation of the remaining circuit. This insures against total loss of braking power due to failure of a single circuit.

Single-circuit steering-assist brake valves Description • Mechanically operated modulating brake valves for steering assist and service braking

• Supplies 2 identical output pressures (P1 and P2) • Used with a single-circuit accumulator charging valve (VB100 for example) Principle of operation VB0B0 actuation is accomplished using two pedals: the right pedal controls the machine right-hand brakes, and the left pedal the machine left-hand brakes. P1

• Work mode (Directional braking right/left)

P2

In work mode both pedals are actuated independently. When the operator depresses either of the two pedals, the VB0B0 supplies precise operating pressure exclusively to the service brake associated to this pedal.

• Road mode (Braking with equal power distribution) In road mode the two pedals are mechanically linked together: when the operator depresses either of the two pedals, the VB0B0 supplies precise and strictly identical operating pressure to the service brakes of both sides of the machine.

Features • 2 identical, adjustable output pressures • Steering-assist / service braking function • Precise, modulated output pressures • Small, lightweight package

• Mechanically operated modulating brake valves for emergency/parking brake actuation

• Used for Inching control • Supplies 1 output pressure • Available with your choice of input: horizontal / vertical levers or pedal type Principle of operation • Power-off controlled braking (negative pressure braking) The VB002 supplies a precise output pressure inversely proportional to the mechanical command position: the pressure from the valve to the Spring-Applied Hydraulically-Released (SAHR) brake decreases, from a max preset pressure that keeps the brake fully released when the command is released, to 0 when the command is actuated.

ACCUMULATOR CHARGING VALVES VB100

Single-circuit accumulator charging valves Description • Supplies 1 output to keep the accumulator under pressure • Supplies 1 output for auxiliaries • Used with single-circuit modulating brake valves Principle of operation Hydraulic energy is stored by maintaining pressure in the accumulator within a preset range (cut-in and cut-out pressures). When accumulator pressure reaches its lower limit (cut-in pressure), a small amount of oil is diverted from the auxiliaries to recharge the accumulator. Once the accumulator pressure reaches the upper limit (cut-out pressure), the valve automatically stops charging the accumulator and resumes full flow to auxiliaries
