The Bosch Rexroth 2FRM6B76-3X/02QRV (R900214482) is a high-quality flow control valve designed to maintain a consistent flow rate regardless of pressure and temperature fluctuations. This particular model, part of the FRM series, is engineered without an external closure and lacks a check valve. It operates by throttling the flow from channel A to B through a set throttle cross-section, which can be adjusted by turning the rotary knob for precise control. The valve features a pressure compensator that ensures a pressure-independent and constant flow in channel B. The compensator automatically adjusts to balance forces when there are changes in pressure, moving into the controlled position to maintain consistent flow rates. A compression spring is integrated into the design to keep the compensator open in no-flow conditions. For applications requiring bidirectional flow control, this valve can be used with a rectifier sandwich plate type ZS. The 2FRM6B76-3X/02QRV conforms to DIN form A for porting patterns and must be paired with subplates ordered separately. Users have options for adjustment types including a rotary knob with scale or a lockable rotary knob with scale for added security. This component has a maximum operating pressure of up to certain bars and can handle maximum flow rates measured in liters per minute (l/min), making it suitable for various hydraulic systems requiring precise flow regulation. The Bosch Rexroth 2FRM6B76-3X/02QRV represents reliable German engineering and is built to deliver consistent performance in demanding 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.

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.
