5-Way Hydraulic Flow Control Valve – Pressure Compensated – 350 bar – Bosch Rexroth

The Bosch Rexroth A-VRFC3C-VEI-VS 5-way flow control valve (code 0M.43.12.80) is a heavy-duty pressure-compensated flow regulator designed for two-pump hydraulic systems.
It provides a stable, solenoid-controlled priority flow while efficiently diverting excess flow to secondary circuits.

Equipped with a built-in relief valve and zinc-plated steel body, this valve ensures long-term reliability in demanding environments.

Operation:

• Two inlets: P1 and P2

• Three outlets:

  • A = priority, pressure-compensated outlet (solenoid-controlled),

  • B1 & B2 = bypass outlets for excess flow.
    All three flows (A, B1, B2) can be used to power different machine functions simultaneously, independently from each other’s working pressures.

This valve is ideal for powering hydraulic tools (such as hammers, cutters, or motors) directly from an existing system — no need to modify the main directional control valve.

Technical data:
