The Bosch Rexroth Z2FS10A5-3X/S2 (R900571890) is a high-performance industrial hydraulic sandwich plate valve designed for precise flow control in hydraulic systems. This mechanically actuated throttle check valve is specifically crafted to provide reliable throttling to a set value, ensuring optimal performance in controlling fluid dynamics. Boasting a robust design, it features a spindle with an internal hexagon and scale for accurate adjustments.
The model Z2FS10A5-3X/S2 comes with the spool symbol A A or A B, indicating its configuration for flow direction control. It can handle a maximum pressure as specified by its product group ID, and offers flexibility with the number of ports available for system integration. The type of actuation is mechanical, which allows for straightforward operation and maintenance.
With its max flow capacity, the valve can efficiently manage system demands while maintaining stability and precision. The connection type adheres to the Sandwich plate standard, ensuring compatibility with industry norms such as NFPA T.. R D SizeCETOP D and ISO standards for porting patterns.
This model features two throttle check valves that are symmetrically aligned to limit flow in one direction while allowing free return flow in the opposite direction. It's suitable for both main flow limitation and pilot flow limitation applications, providing versatility across different hydraulic circuit designs. The adjustment types include options such as a lockable rotary knob with scale or a rotary knob with scale, offering meter-in or meter-out throttling based on system requirements.
The corrosion-protected design extends the valve's service life even in harsh operating environments. Its size and component series X are indicative of its capacity to withstand maximum operating pressures up to a certain bar level while handling maximum flows measured in liters per minute.
Overall, the Bosch Rexroth Z2FS10A5-3X/S2 valve is engineered for reliability and precision control within various hydraulic applications where accurate flow regulation is critical.

The valve type Z2FS 10 is a throttle check valve in sandwich plate design. It is used for the main or pilot flow limitation of one or two actuator ports.
Two throttle check valves aligned symmetrically to each other limit flows in one direction and allow free return flow in the opposite direction.
In case of supply throttling, the hydraulic fluid is directed through channel A1 via throttling point (1) formed by the control edge (2) and the throttle spool (3.1) to actuator A2. The throttle spool (3.1) can be axially adjusted via the spindle (4) for adjustment of the throttling point (1).
Simultaneously, the hydraulic fluid in channel A1 is directed via the bore (5) to the piston side (6). The active pressure and the spring force retain the throttle spool (3.1) in throttle position.
The hydraulic fluid return flow from actuator B2 displaces the throttle spool (3.2) against the spring (7) and enables the unobstructed flow as check valve. Depending on the installation position, the throttling effect may occur in supply or discharge.
Main flow limitation
For actuator velocity adjustment (main flow limitation), the throttle check valve is installed between the directional valve and the subplate.
Pilot flow limitation
With pilot-operated directional valves, the throttle check valve can be applied for switching time adjustment (pilot flow limitation). In this case, it is installed between the pilot control valve and the main valve.
