The Bosch Rexroth Z2FRM6AB2-2X/6QRV (R900910906) is a sophisticated flow control valve designed for stabilizing flow in hydraulic systems irrespective of pressure and temperature variations. This sandwich plate valve is notable for its dual flow control cartridges housed within a robust body, facilitating precise throttling from channel AB to AB. Users can adjust the throttle cross-section by rotating the internal hexagon adjustment type, which interacts with the throttle bolt and throttling point to regulate fluid flow.
Incorporated into the design is a pressure compensator that ensures pressure-independent stabilization in channel AB. It operates dynamically; as the flow initiates, it moves into a control position to balance forces within the system. Any increase in pressure prompts the compensator to adjust accordingly, maintaining a consistent flow rate. The valve also features a check valve allowing free return flow from channel AB back to channel AB.
The Z2FRM6AB2-2X/6QRV conforms to DIN and ISO porting patterns with options for locating holes, ensuring compatibility with various industrial standards. It can be equipped with either one or two flow control cartridges based on application requirements. This model boasts an impressive maximum operating pressure of up to 315 bar and can handle maximum flows of up to 60 l/min, showcasing its capability to operate effectively under demanding conditions.
Overall, this Bosch Rexroth valve offers reliable performance for applications requiring meticulous flow management within hydraulic circuits, making it an essential component for ensuring optimal system functionality.

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).
