The 3FREZ6B-1X/10L2G24-27Z4MM-254 valve belongs to the 3FRE Flow Control Valves series produced by Bosch Rexroth for precise hydraulic automation. It is a proportional flow control valve that meters oil in proportion to an electrical command. The nominal size is NG6, allowing installation in compact manifolds. A mounting interface that follows ISO 4401-03-02-0-94 permits direct stacking on standardized subplates. The valve delivers a nominal flow of 10 l/min at a differential pressure of 8 bar, giving predictable actuator speed. A linear flow characteristic keeps the volume change directly proportional to spool position. The unit tolerates working pressures up to 250 bar, matching medium-pressure power units, and it is designed for mineral oil in the HL or HLP classes to preserve seal integrity and lubrication.
On-board electronics eliminate the need for an external amplifier and operate from a 24 V DC supply. The electronics accept a 0…+10 V normally closed setpoint input and use inductive position feedback to maintain accurate spool travel. Electrical connection is provided through a 6P+PE interface, and wiring terminates in a DIN 43563-AM6 plug connector for quick replacement. NBR seals contain the fluid and resist common mineral oils under operating temperature. The valve is supplied without a non-return valve, so reverse flow must be managed elsewhere in the circuit.
