The Bosch Rexroth 2FRM6A76-3X/10QMV (R900209925) is a high-performance flow control valve designed for maintaining a consistent flow rate regardless of fluctuations in pressure and temperature. This particular model features a sturdy housing, an adjustable rotary knob, an orifice bush, and a pressure compensator, along with an optional check valve for versatile application use. The 2FRM6A76-3X/10QMV is equipped with the capability for external closure of the pressure compensator via channel P, which allows for improved control by holding the compensator closed against a compression spring through external pressure. This version of the flow control valve is specifically intended for supply control applications and includes the functionality to avoid startup jumps when switching directional valves from P to B. The free return flow from channel B to channel A is managed by the optional check valve, ensuring efficient operation. It's important to note that any pressure loss from port P upstream of the directional valve to port A upstream of the flow control valve will result in reduced flow. The Bosch Rexroth 2FRM6A76-3X/10QMV conforms to DIN form A for porting patterns and requires subplates which are ordered separately. Users can select from adjustment types such as a rotary knob with scale or a lockable rotary knob with scale, according to their specific needs. The component series X indicates that this model can withstand maximum operating pressures up to bar levels and can handle maximum flows up to l/min, making it suitable for various hydraulic applications demanding precise flow regulation under changing conditions.

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.
