The Bosch Rexroth 2FRM10-3X/50LBV (R900424898) is a high-performance industrial hydraulic valve designed for reliable control of flow to a set value. This direct-actuated valve features a pressure compensator with optional stroke limitation and a lockable rotary knob with scale, ensuring precise adjustments can be made and maintained. The spool symbol A → B, B → A indicates the directionality of the flow control.
With a maximum pressure product group ID and multiple ports, this valve is mechanically actuated and has the capability to handle a maximum flow rate as specified by its design. It offers subplate mounting with connection diagrams conforming to ISO standards and features several switching positions. The valve's weight is listed along with its seals made from FKM, making it suitable for various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
Flow control valves such as the Bosch Rexroth FRM series are typically used to maintain a consistent flow rate that is largely independent of pressure and temperature fluctuations. They achieve temperature independence through an orifice design at the throttling point. Additionally, free return flow from channel B to A is facilitated by an integrated check valve.
This model ensures regulated flow only in one direction from channel A to B but can accommodate oscillating flows in both directions when paired with a rectifier sandwich plate type ZS installed underneath it. Designed for subplate mounting with porting patterns according to DIN form G and ISO standards, this valve includes mechanical actuation along with pressure compensator stroke limitation that can be optionally included. The unit also features startup jump reduction and allows for controlled flow in both directions through the rectifier sandwich plate. It comes in size 10 of component series X with specified maximum operating pressure (bar) and maximum flow rate (l/min).

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.
