The Bosch Rexroth 2FRM6SB36-3X/3QMV (R900221109) is a high-performance industrial hydraulic valve designed for precise flow control in hydraulic systems. This direct-acting valve is intended for control panel installation and features a lockable rotary knob with scale, allowing for accurate adjustments to flow settings. It does not include a pressure compensator closure or a check valve, which provides flexibility in applications where these functions are not required or are provided separately. The 2FRM6SB36-3X/3QMV valve operates by mechanically throttling the flow from channel A to B, ensuring a constant and pressure-independent flow rate. The design includes an orifice bush and a pressure compensator that work together to balance forces and maintain steady operation despite varying pressures. The rotary knob's lockable feature ensures that settings remain secure during operation. This model boasts a spool symbol indicating the A to B and B to A functionality, which is essential for controlling the direction of fluid within the system. It is equipped with threaded connections conforming to ISO standards, ensuring compatibility with various hydraulic setups. The number of ports and switching positions align with industry requirements, while FKM seals provide compatibility with an extensive range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. The Bosch Rexroth 2FRM6SB36-3X/3QMV valve is characterized by its robust construction and reliable performance in demanding environments. Its compact size allows for integration into systems where space is at a premium without sacrificing flow capacity or maximum operating pressure capabilities. This specific model is part of Bosch Rexroth's broader product lineup designed to offer precise control for various industrial applications.

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 SB…RV

(without external closing, with check valve, with threaded connectionfor control panel installation)

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.

The free return flow from channel B to channel A is directed via the check valve (8).
