The Bosch Rexroth 2FRM6B36-3X/3QMV (R900205516) is a high-performance industrial hydraulic valve designed for precise flow control in a variety of applications. This direct-actuated valve offers reliable control of flow to a set value without the use of a check valve. It features a lockable rotary knob with scale, allowing for easy and accurate adjustments. The spool symbol indicates A to B and B to A functionality, enabling controlled flow in both directions. With its robust design, the 2FRM6B36-3X/3QMV can withstand maximum pressures, ensuring durability and long-term performance. The valve is mechanically actuated and does not require closing of the pressure compensator. It is suitable for subplate mounting and follows the ISO connection diagram standards. The number of ports and max flow specifications cater to various system requirements, while the FKM seals offer compatibility with a wide range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. This versatility makes it an ideal choice for diverse hydraulic systems seeking consistent flow regulation despite changes in pressure and temperature. The Bosch Rexroth 2FRM6B36-3X/3QMV valve's construction includes a housing unit, orifice bush, and pressure compensator that work together to maintain steady flow rates through mechanical actuation. For bidirectional control capabilities, an additional rectifier sandwich plate type ZS can be installed beneath this valve. Overall, this model is characterized by its ease of operation with options such as a rotary knob or lockable rotary knob with scale for precise adjustments. Its size and series reflect its capacity to handle maximum operating pressures and flows efficiently within industrial settings requiring dependable hydraulic fluid management without compromise on performance or reliability.

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.
Flow control valve type 2FRM 6 B…MV
(without external closing, without check valve)
The flow from channel A to channel B is throttled at the throttling point (5). The throttle cross-section is set by turning the rotary knob (2). To ensure a pressure-independent and constant flow in channel B, a pressure compensator (4) is fitted downstream of the throttling point (5).
The compression spring (6) presses the pressure compensator (4) downwards against its stop and keeps the pressure compensator (4) in the open position when there is no flow through the valve. When fluid flows through the valve, the pressure acting in channel A applies a force to the pressure compensator (4) via orifice (7).
The pressure compensator (4) moves into the controlled position until the forces balance. If the pressure in channel A rises, the pressure compensator (4) moves in the closing direction until the forces are balanced again. Due to this continuous compensation of the pressure compensator (4), a constant flow is obtained.
In order to control a flow through the valve in both directions, a rectifier sandwich plate type Z4S 6 may be fitted below this flow control valve.
