The Bosch Rexroth Z2FRM6AB0-2X/16QMV (R900909856) is a high-quality flow control valve designed for precise flow stabilization in hydraulic systems, regardless of pressure and temperature variations. This sandwich plate valve is engineered to maintain a consistent flow rate by employing one or two flow control cartridges housed within its robust frame. The throttling from channel AB to channel AB occurs at a designated throttling point, with the throttle cross-section being adjustable via rotation of the adjustment type.
A key feature of this model is its pressure compensator, which ensures pressure-independent flow stabilization. The compensator reacts dynamically to changes in flow, adjusting its position to balance forces and maintain a constant flow rate even when channel AB's pressure fluctuates. This continuous compensation mechanism is facilitated by a compression spring that keeps the pressure compensator in an open position when idle and prompts it to adjust as necessary during operation.
Additionally, the Z2FRM6AB0-2X/16QMV valve facilitates free return flow from channel AB to channel AB through an integrated check valve. It adheres to international standards with porting patterns according to DIN form A and ISO with locating hole, ensuring compatibility with various hydraulic systems.
This model comes equipped with either one or two flow control cartridges and features an adjustment type with an internal hexagon for easy configuration. With a maximum operating pressure of 315 bar and a maximum flow rate of 16 liters per minute, this valve is suitable for diverse applications that require reliable and stable fluid management. The Z2FRM6AB0-2X/16QMV represents component series X, signifying its place within Bosch Rexroth's line of advanced hydraulic components designed for efficiency and performance.

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).
