The Bosch Rexroth 2FRM6B36-3X/3QRV (R900205517) is a high-performance industrial hydraulic valve designed for precise flow control in hydraulic systems. This direct-actuated valve features a spool symbol for A to B and B to A configurations and includes a built-in check valve. It is notable for its reliable control of flow to the set value without pressure compensator closure. Users can adjust the flow rate via a lockable rotary knob that comes with an easy-to-read scale, ensuring accurate settings. The 2FRM6B36-3X/3QRV valve is characterized by its mechanical actuation, making it suitable for applications requiring robust and reliable performance. With CETOP D subplate mounting, this model follows the NFPA T.. R D Size and ISO connection diagrams, facilitating compatibility with standard hydraulic systems. The valve can handle a maximum operating pressure and offers an optimal flow rate. Constructed with FKM seals, this Bosch Rexroth valve is compatible with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Its design ensures maintenance of a constant flow irrespective of pressure fluctuations or temperature changes within the system. The durable construction and materials used in the 2FRM6B36-3X/3QRV make it suitable for demanding industrial environments where consistent flow control is critical. In summary, the Bosch Rexroth 2FRM6B36-3X/3QRV (R900205517) is an efficient solution for users seeking precise control over their hydraulic system's flow rates in both directions through mechanically actuated means. Its robust design and compatibility with various fluids make it an essential component in industrial settings requiring dependable hydraulic 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.
