The 2FRM6B36-3X/1.5QRV flow control valve is part of the 2F Flow Control Valves series produced by Bosch Rexroth for hydraulic automation circuits. This model is a size 6, 2-way flow control unit that meters oil in both A→B and B→A directions to stabilize actuator speed. Direct mechanical actuation removes the need for a pilot line, and a lockable rotary knob with an indexed scale provides repeatable throttling adjustment. The valve follows a progressive flow characteristic, so small knob movements give fine resolution at low flow rates. A built-in check valve permits free reverse flow, enabling bypass during retraction or return strokes. The CETOP 3 (D03) mounting interface matches subplates in compact manifolds, and the porting pattern complies with DIN 24340 Form A.
The 2FRM6B36-3X/1.5QRV handles a rated flow of 1.5 l/min from port a to b and allows peaks up to 32 l/min without cavitation when the bypass path is open. Continuous service is possible at operating pressures up to 315 bar. The internal pressure compensator works without an external closing line, maintaining the selected flow despite load changes. FKM seals resist high temperature and aggressive fluids, extending service intervals. The valve’s DIN-standard subplate layout allows replacement with only four screws and no pipework changes, supporting rapid maintenance in modular stacks.
