The Bosch Rexroth 2FRM6A36-3X/15QRV (R900205503) is a highly precise and mechanically actuated industrial hydraulic valve, designed for reliable control of flow to a set value. This direct-actuated valve features a lockable rotary knob with scale, facilitating accurate adjustments, and includes a check valve for unidirectional flow control. With its spool symbol indicating A to B and B to A functionality, this model ensures versatility in managing hydraulic flows. The 2FRM6A36-3X/15QRV valve is characterized by its robust performance with a maximum pressure capacity and an optimal flow rate. It offers subplate mounting with an ISO connection diagram for ease of integration into various systems. The number of ports and the type of actuation—which is mechanical—further define this component's capabilities within hydraulic circuits. This model is compatible with a wide range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, HFDR thanks to its FKM seals which ensure durability against different fluid types. The size and weight specifications make it suitable for applications where space considerations are critical. In summary, the Bosch Rexroth 2FRM6A36-3X/15QRV offers consistent flow regulation in hydraulic systems while allowing for external pressure compensation closure via channel P. Its design caters to supply control applications where precision is paramount. The optional check valve enhances its functional flexibility by enabling free return flow from channel B to A without compromising the system's performance or efficiency.

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.
