The Bosch Rexroth 2FRM6B36-3X/06QRV (R900211380) is a high-performance industrial hydraulic valve designed for precise flow control in hydraulic systems. This mechanically actuated valve ensures consistent flow regardless of pressure fluctuations and temperature variations, thanks to its integrated pressure compensator and optional check valve. The model features a lockable rotary knob with a scale for accurate adjustments and can be used in applications where the control of fluid direction from A to B and B to A is required. With a maximum operating pressure of 315 bar and capable of handling a maximum flow rate as specified by the user, this valve is robust and reliable for industrial use. It comes with FKM seals, making it suitable for various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, HFDR. The 2FRM6B36-3X/06QRV is designed for subplate mounting with connection conforming to ISO standards. The unit's compact size allows for ease of integration into existing hydraulic systems while maintaining performance and reliability. Its direct actuation feature excludes the need for closing the pressure compensator which simplifies operation. The spool symbol indicates the direction of flow from A to B or B to A when actuated. This Bosch Rexroth flow control valve is an essential component for applications requiring precise control over hydraulic system flow rates while ensuring minimal impact from external variables on system performance.

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.
