The Bosch Rexroth Z2FRM6CB2-2X/6QRV (R900910904) is a sophisticated flow control valve designed for stabilizing flow rates in hydraulic systems irrespective of pressure and temperature variations. This sandwich plate valve is engineered to be mounted between standardized porting patterns according to DIN and ISO norms, ensuring compatibility with a wide range of equipment setups. It features one or two flow control cartridges that enable precise throttling from channel AB to AB by adjusting the throttle cross-section through rotation.
Incorporated within the design is a pressure compensator that ensures pressure-independent flow stabilization. The compensator reacts dynamically to changes in flow, adjusting its position to maintain a consistent rate of flow even when there are fluctuations in pressure within channel AB. This is achieved through a balance of forces between the compression spring and the plug screw, resulting in the continuous compensation characteristic of this model.
Furthermore, the Z2FRM6CB2-2X/6QRV allows free return flow from channel AB back to channel AB via an integrated check valve, thereby enhancing its functionality as a bidirectional control unit. The adjustment type comes with an internal hexagon for easy setting adjustments, and it is built to withstand maximum operating pressures up to bar while handling maximum flows up to l/min. With its robust construction and reliable performance, this Bosch Rexroth valve represents an essential component for maintaining efficient and stable hydraulic operations across various applications.

The valve type Z2FRM is a 2-way flow control valve in sandwich plate design. It is used for pressure and temperature-independent flow stabilization.
The valves basically consist of housing (1) and one or two flow control cartridges.
Throttling of the flow from channel A➁/B➁ to channel A➀/B➀ is realized at the throttling point (3). The throttle cross-section is set by rotation of the adjustment type (2) between the throttling point (3) and the throttle bolt (4).
For pressure-independent flow stabilization in channel A➀/B➀, a pressure compensator (5) is connected downstream to the throttling point (3).
The pressure compensator (5) is pressed by the compression spring (7) against the plug screw (8) and remains in open position if there is no flow through the valve. When there is a flow through the valve, the pressure in channel A➁/B➁ applies a force on the pressure compensator (5). It is set to control position until the forces are balanced. If the pressure in channel A➁/B➁ rises, the pressure compensator (5) moves in closing direction until the forces are balanced again. Due to this continuous compensation of the pressure compensator, a constant flow is obtained.
The free return flow from channel A➀/B➀ to channel A➁/B➁ is via the check valve (6).
