The Bosch Rexroth 2FRM6A76-3X/3QRV (R900226906) is a high-quality flow control valve designed for maintaining a constant flow regardless of pressure and temperature fluctuations. This 2-way flow control valve features a robust housing, a user-friendly rotary knob, an orifice bush, and a pressure compensator. Additionally, it includes an optional check valve for enhanced functionality. This model, 2FRM6A76-3X/3QRV, is equipped with external closing capabilities allowing the pressure compensator to be externally closed via channel P. This design ensures that when the connected directional valve allows flow from P to B, the startup jump is eliminated, providing smooth operation. It's important to note that this version is specifically intended for supply control applications. The free return flow from channel B to channel A smoothly passes through the check valve when integrated. Users can benefit from different adjustment options including a rotary knob with scale or a lockable rotary knob with scale for precise flow regulation. Moreover, the 2FRM6A76-3X/3QRV adheres to the DIN form A porting pattern and requires subplates which are ordered separately. It boasts a maximum operating pressure of up to X bar and can handle maximum flows of up to l/min. The potential pressure loss between port P upstream of the directional valve and port A upstream of the flow control valve should be considered as it may result in reduced flow. This Bosch Rexroth valve is engineered for reliability and consistent performance in various hydraulic applications where precise flow control is essential. Its thoughtful design characteristics make it suitable for systems requiring external intervention on the pressure compensator and those that benefit from optional check valves for unidirectional free flow return paths.

General information

The flow control valve type 2 FRM is a 2-way flow control valve.

It is used for maintaining a constant flow, independent of pressure and temperature.

The valve basically consists of housing (1), rotary knob (2), orifice bush (3), pressure compensator (4) and an optional check valve (8).

Flow control valve type 2FRM 6 A…RV

(with external closing, with check valve)

In principle, the function of this valve is the same as that of valve type 2FRM 6 B…MV.

However, the flow control valve is provided with the possibility of an external closing of the pressure compensator (4) via channel P (9). The external pressure acting in channel P (9) via orifice (10), holds the pressure compensator (4) in closed position against the compression spring (6). When the connected directional valve (11) is switched over to permit flow from P to B, control is achieved as with type 2FRM 6 B. Thus, a start-up jump is avoided.

The version with pressure compensator closing can only be used for supply control.

The free return flow from channel B to channel A is directed via the check valve (8).

Attention!

The pressure loss of port P upstream of the directional valve to port A upstream of the flow control valve makes itself felt by a reduced flow.
