Hydraulic Flow Control Valve 3-Way – Priority A, Bypass B1/B2 – 350 bar

The 0M.43.12.80 3-way hydraulic flow control valve provides efficient and accurate flow distribution for hydraulic systems requiring simultaneous, independent operations.

It features two separate inlets (P1 and P2) and three outlets (A, B1, B2):

• Port A is the priority, pressure-compensated outlet, equipped with a built-in relief valve and solenoid cartridge for on-demand activation.

• Ports B1 and B2 act as bypass lines, carrying excess flow to other hydraulic functions.

This valve design allows powering multiple hydraulic circuits simultaneously, such as:

• the priority actuator through A,

• and the machine’s normal functions (traction, slewing, lifting, etc.) through B1/B2, without pressure interference.

It provides a simple and effective way to power hydraulic tools (like hammers or cutters) from an existing hydraulic system — no need to modify the main directional valve.
