***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth 2FRM10-3X/16QB (R900434256) is a meticulously engineered flow control valve designed to maintain a consistent flow rate, largely unaffected by fluctuations in pressure and temperature. This valve incorporates a robust housing and an orifice bush, with a pressure compensator that can be optionally fitted with stroke limitation for precise control. The integrated check valve ensures unidirectional regulated flow from channel A to B, while the free return flow is managed via the same check valve. This model features mechanical actuation and includes a geared piston drive equipped with an adjustable stroke limitation, allowing for fine-tuning of the positioning velocity through the throttle check valve. The design of this valve ensures temperature stability by utilizing an orifice design at the throttling point. For applications requiring oscillating flows, this valve can accommodate forward and return flows through the installation of a rectifier sandwich plate type ZS beneath it. The 2FRM10-3X/16QB is designed for subplate mounting with porting patterns conforming to DIN form G and ISO standards. This particular model falls under component series X, indicating its place within Bosch Rexroth's lineup of high-quality hydraulic components. It supports a maximum operating pressure of up to several hundred bar and can handle maximum flow rates in liters per minute as specified in its technical documentation. With these specifications, the Bosch Rexroth 2FRM10-3X/16QB flow control valve stands as an essential component for hydraulic systems requiring precise flow management under varying operational conditions.

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.
