The Bosch Rexroth 2FRM10-3X/25LB (R900423256) is a high-performance, industrial hydraulic valve designed for precise flow control within hydraulic systems. This mechanically actuated valve is equipped with a pressure compensator and stroke limitation, ensuring reliable performance even under varying pressure conditions. It features a lockable rotary knob with a scale for accurate adjustments and is marked by its direct actuation capabilities.
The 2FRM10-3X/25LB valve's spool symbol indicates the flow direction from A to B and B to A, suitable for applications requiring controlled flow in both directions. With its maximum pressure capacity and subplate mounting design conforming to DIN form G and ISO standards, the valve ensures robust operation in demanding environments. The number of ports and the type of connection are specified by the product group ID, ensuring compatibility with various hydraulic systems.
This model boasts a max flow rate that can be adjusted via the mechanically turned curved bolt over the adjustment element, which interacts with the geared piston drive for precise control of positioning velocity. The addition of an adjustable stroke limitation on the geared piston drive allows users to set and fix required adjustment ranges easily.
Temperature fluctuations do not affect valve performance due to its orifice design at the throttling point, which guarantees temperature independence. Furthermore, free return flow from channel B to channel A is facilitated through an integrated check valve.
For applications involving oscillating flows, an optional rectifier sandwich plate type ZS can be installed beneath this flow control valve to ensure consistent control in both forward and return directions. Hydraulic fluid compatibility includes HL, HLP, HLPD, HVLP, HVLPD, and HFC types with NBR seals contributing to its versatility across different system requirements.

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.
