The Bosch Rexroth Z2FS10B3-3X/SV (R900057401) is a high-performance industrial hydraulic valve designed for reliable flow throttling to a preset value. This valve is characterized by its direct actuation and the ability to be mechanically actuated. It features a lockable rotary knob with a scale for precise adjustments. The Z2FS10B3-3X/SV is part of the ZFS series, which are throttle check valves in sandwich plate design, typically used for controlling the main or pilot flow limitation of one or two actuator ports.
The valve incorporates two symmetrical throttle check valves that limit flow in one direction while allowing free return flow in the opposite direction. The design ensures that hydraulic fluid is directed efficiently, with an adjustable throttle spool to control the flow rate. The throttle spool's position is maintained by both pressure and a spring force, which together ensure consistent throttling performance.
For applications requiring main flow limitation, this valve can be installed between the directional valve and subplate to adjust actuator velocity. Additionally, it can serve as a pilot flow limiter by being placed between the pilot control valve and main valve for switching time adjustment.
The Bosch Rexroth Z2FS10B3-3X/SV has various adjustment types including a lockable rotary knob with scale, spindle with internal hexagon and scale, and rotary knob with scale. It supports both meter-in and meter-out throttling and boasts corrosion-resistant construction. With its CETOP D size porting pattern according to ISO standards, it can handle maximum operating pressures up to bar and maximum flows of l/min. The seals are made from FKM material suitable for various hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, HFDR to ensure compatibility with different system requirements.

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.
