The 3FRM10-2X/25L is manufactured by Bosch Rexroth and belongs to the 3FRE Flow Control Valves series. It regulates hydraulic flow in automated machinery where stable volume delivery is needed. Mechanical actuation lets an operator set the spool position directly, and the 3-way flow control function splits inlet flow while maintaining constant output. Nominal size 10 matches CETOP 03 subplates for common manifold layouts, and a rated flow of 25 l/min supports medium-capacity circuits. Because the flow characteristic is linear, every degree of knob rotation produces a proportional change in flow. A 300° turning range spans the full adjustment window, while ten scale divisions on the dial assist precise repeat settings. The valve can be installed in any orientation, so designers can position it wherever access is convenient.
Subplate mounting simplifies maintenance because the body lifts off the manifold without disturbing pipework, and four ISO 4762 M8 × 50 screws secure it against pressure loads. The unit tolerates operating pressures up to 315 bar, allowing it to work in high-pressure power packs. NBR seals contain mineral-oil media and hold pressure over long duty cycles. The design is supplied without a pressure relief valve, so the system must include external over-pressure protection, and it also lacks an unloading port, meaning pump flow cannot be vented through the housing. Cleanliness class 20/18/15 per ISO 4406 limits allowable particle contamination and guides filter selection for long service life. Finally, a weight of 3.3 kg permits one-person handling during installation or replacement.
