The Bosch Rexroth 2FRM6SB76-3X/16QMV (R901332323) is an industrial hydraulic valve designed for precise flow control within a hydraulic system. This valve is a size 6, mechanically actuated flow control valve that provides reliable performance by maintaining a constant flow regardless of pressure changes or temperature variations. It features direct actuation without the need for closing the pressure compensator, making it suitable for control panel installation. Equipped with a rotary knob and scale, operators can easily adjust and set the desired flow rate. The model does not include a check valve, which means it allows free flow in one direction. The spool symbol for this valve is A ↔ B, B ↔ A, signifying its bidirectional capability. The 2FRM6SB76-3X/16QMV is built to handle maximum pressures efficiently and comes with FKM seals that are compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Its threaded connection ensures secure attachment within the hydraulic circuit. This model's design includes an orifice bush and a pressure compensator to guarantee consistent flow rates even when external conditions vary. The compensator adjusts fluid passage to balance out any fluctuations in channel A's pressure to maintain steady operation. With its robust construction and reliable performance characteristics, the Bosch Rexroth 2FRM6SB76-3X/16QMV valve is an essential component for systems requiring precise flow control without sacrificing efficiency or performance stability.

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).
