The Bosch Rexroth 2FRM6A36-3X/6QRV (R900205505) is a high-performance industrial hydraulic valve designed for precise flow control in a variety of applications. This direct-actuated valve features a spool symbol A to B and B to A, ensuring reliable control of flow to the set value. The lockable rotary knob with scale allows for accurate adjustments, while the integrated check valve maintains system integrity. With its mechanical actuation, the 2FRM6A36-3X/6QRV offers robust performance and responsiveness. The valve is equipped with a pressure compensator that can be closed externally, allowing for consistent operation even under fluctuating pressure conditions. This feature also helps prevent startup jumps when controlling supply flow. The unit is designed for subplate mounting and conforms to ISO connection diagrams, simplifying installation and maintenance. It supports various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR with FKM seals to accommodate different system requirements. This model has multiple ports and switching positions that cater to specific system configurations. It boasts a maximum operating pressure and flow rate that are suitable for demanding industrial environments. The 2FRM6A36-3X/6QRV's design includes features like external closing of the pressure compensator and optional adjustment types like the rotary knob with scale or lockable rotary knob with scale. Overall, the Bosch Rexroth 2FRM6A36-3X/6QRV offers a reliable solution for maintaining constant flow rates in complex hydraulic systems where precision is paramount. Whether it's used in manufacturing equipment or other industrial applications requiring meticulous fluid control, this valve stands out for its efficiency and adaptability.

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.
