The Bosch Rexroth 2FRM10-3X/16LB (R900423252) is a precision-engineered flow control valve designed to regulate fluid flow with high consistency, largely unaffected by pressure and temperature variations. This valve is particularly well-suited for applications requiring a constant flow rate, thanks to its robust construction that includes a housing, orifice bush, and pressure compensator with an optional stroke limitation. The check valve ensures free return flow from channel B to A, while the adjustment element allows for precise mechanical setting of the throttle cross-section by turning the curved bolt. With its geared piston drive equipped with an adjustable stroke limitation, users can fine-tune the positioning velocity via the throttle check valve and secure the desired adjustment range. The upstream pressure compensator further contributes to maintaining a steady and pressure-independent flow at the throttling point. The 2FRM10-3X/16LB achieves temperature independence through its specialized orifice design at the throttling point. Although regulated flow is unidirectional from channel A to B, for applications involving oscillating flows, a rectifier sandwich plate type ZS can be installed beneath the valve to allow controlled flow in both directions. Designed for subplate mounting with porting patterns conforming to DIN form G and ISO standards, this Bosch Rexroth valve offers flexibility in installation. It features mechanical actuation and comes with options like startup jump reduction and pressure compensator stroke limitation. With a maximum operating pressure of up to bar and a maximum flow rate of l/min, this component series X size valve stands out for its reliability in various hydraulic systems where precise flow control is paramount.
Flow control valves type 2FRM are 2-way flow control valves. They are used to maintain a constant flow, mostly independent of pressure and temperature.
Generally, the valves consist of housing (1), orifice bush (2), pressure compensator (3) with optional stroke limitation (3.1), check valve (4), adjustment element (5) at type 2FRM as well as geared piston drive (6), and directional valve (7). The flow from channel A to channel B is throttled at the throttling point (9). The throttle cross-section of type 2FRM is set by mechanically turning the curved bolt (10) over the adjustment element (5). The positioning velocity can be set by means of the throttle check valve (6.3 and 6.4). To fix the required adjustment range, the geared piston drive (6) is equipped with an adjustable stroke limitation (6.1 and 6.2) on both sides. An upstream pressure compensator (3) is included to ensure a pressure-independent and constant flow at throttling point (9).
Temperature independence is achieved thanks to the orifice design of the throttling point.
The free return flow from channel B to channel A is directed via the check valve (4).
The regulated flow only flows from channel A to B.
For oscillating flows (forward and return flow), a rectifier sandwich plate type Z4S can be installed under the flow control valve.

Important information on hydraulic fluids! For further information and data on the use of other hydraulic fluids, please refer to data sheet 90220 or contact us! There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.)! The flash point of the hydraulic fluid used must be 40 K higher than the maximum solenoid surface temperature. Flame-resistant – containing water: Maximum pressure differential per control edge 50 bar. Pressure pre-loading at the tank port >20% of the pressure differential; otherwise, increased cavitation Life cycle compared to operation with mineral oil HL, HLP 50 to 100 % Bio-degradable: When using bio-degradable hydraulic fluids that are zinc-solving, zinc may accumulate in the fluid (700 mg zinc per pole tube) |
