The Bosch Rexroth 2FRM16-3X/60LBV (R900428280) is a high-quality flow control valve designed for maintaining a consistent flow rate, largely unaffected by pressure and temperature variations. The valve features a robust housing, an orifice bush, and a pressure compensator with an optional stroke limitation that allows for precise control of the hydraulic flow. With its integrated check valve and adjustment element, the 2FRM16-3X/60LBV ensures that flow from channel A to channel B is effectively throttled according to requirements.
The mechanical actuation of this valve is facilitated through a geared piston drive which comes with an adjustable stroke limitation to set and maintain the desired adjustment range. This feature is particularly beneficial in applications where precise flow regulation is critical. The pressure compensator included in the design guarantees a pressure-independent and constant flow at the throttling point, enhancing the valve's performance stability.
To accommodate temperature fluctuations without affecting performance, the orifice design at the throttling point has been optimized for temperature independence. Additionally, free return flow from channel B to channel A bypasses through the check valve without any hindrance.
The 2FRM16-3X/60LBV is engineered to regulate flow exclusively from channel A to B. However, for applications involving oscillating flows with both forward and return movement, an optional rectifier sandwich plate type ZS can be installed underneath the flow control valve to facilitate controlled flow in both directions.
This Bosch Rexroth valve is designed for subplate mounting with porting patterns conforming to DIN form G and ISO standards. It offers mechanical actuation alongside optional features such as pressure compensator stroke limitation and startup jump reduction. The unit's specifications include a size designation of 16, component series X indicating its latest iteration, maximum operating pressure capability of up to bar units, and maximum flow capacity measured in liters per minute.

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.
