The Bosch Rexroth Z2FS10B5-3X/S2VSO30 (R900061121) is a high-performance industrial hydraulic valve designed for precise flow control in hydraulic systems. This direct-actuated, sandwich plate valve features a spindle with an internal hexagon and scale for accurate adjustments. It is equipped with spool symbols B B or B B, indicating its mechanical actuation capabilities.
The Z2FS10B5-3X/S2VSO30 valve offers reliable throttling to a preset value and includes two throttle check valves that are symmetrically aligned to control flow in one direction while allowing free return flow in the opposite direction. The design facilitates main or pilot flow limitation for one or two actuator ports through an efficient supply throttling system. The throttle spool can be adjusted axially via the spindle, enhancing the precision of the throttling point.
This model is designed with a maximum pressure tolerance and conforms to NFPA T.. R D and CETOP D connection diagrams, as well as ISO porting patterns. It can accommodate various types of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR thanks to its FKM seals.
The Z2FS10B5-3X/S2VSO30 valve's versatility extends to its installation options; it can be used between directional valves and subplates for actuator velocity adjustment via main flow limitation or between pilot control valves and main valves for switching time adjustment in pilot flow limitation scenarios. Its corrosion-protected design ensures durability even in harsh working environments.
With multiple adjustment types available such as lockable rotary knobs with scales and meter-in or meter-out throttling options, this Bosch Rexroth valve provides users with flexible configuration choices for optimal control of hydraulic flows within their systems.

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.
