The Bosch Rexroth Z2FS10B5-3X/S2 (R900989106) is a throttle check valve designed for precise flow control in hydraulic systems. This sandwich plate valve is engineered to limit the main or pilot flow to one or two actuator ports, ensuring optimal performance in various applications. The Z2FS10B5-3X/S2 features two symmetrically aligned throttle check valves that restrict flow in one direction while allowing free return flow in the opposite direction.
When supply throttling is employed, the hydraulic fluid passes through channel A and is regulated by the interaction between the control edge and the adjustable throttle spool. The spool's position can be fine-tuned via an axially adjustable spindle to set the desired throttling point. The return flow from the actuator displaces the spool against a spring force, functioning as an unobstructed check valve.
For applications requiring main flow limitation, this valve can be installed between the directional valve and subplate to adjust actuator velocity. In configurations where pilot-operated directional valves are used, it serves to modify switching times by being positioned between the pilot control valve and main valve.
The Z2FS10B5-3X/S2 offers various adjustment types including a lockable rotary knob with scale, spindle with internal hexagon and scale, and rotary knob with scale for precise meter-in or meter-out throttling. It has a corrosion-protected design enhancing its durability for long-term use. Additionally, it adheres to ISO porting pattern standards and can support a maximum operating pressure of up to bar and accommodate maximum flow rates of l/min. This combination of features makes it suitable for a wide range of hydraulic applications where accurate flow control is crucial.

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.
