The Bosch Rexroth Z2FS10A7-3X/S2V (R900032241) is a high-performance throttle check valve designed for precision flow control in hydraulic systems. This sandwich plate valve is engineered to regulate the main or pilot flow limitation of one or two actuator ports with exceptional accuracy and reliability. It features two symmetrically aligned throttle check valves that permit flows in one direction while providing free return flow in the opposite direction, ensuring smooth operation of hydraulic actuators. With its versatile design, the Z2FS10A7-3X/S2V can be used for both supply throttling and pilot flow limitation. The throttle spool within the valve can be finely adjusted via an axially positioned spindle, allowing for precise control over the throttling point and subsequently, the actuator's velocity. This adjustment can be made through various methods including a lockable rotary knob with scale, a spindle with internal hexagon and scale, or a simple rotary knob with scale. The valve's porting pattern is compliant with ISO standards, which ensures compatibility and ease of integration into existing hydraulic systems. Additionally, it boasts a corrosion-protected design that enhances its durability and longevity even in harsh working environments. With a size component series X, this model can sustain a maximum operating pressure of up to several hundred bars and accommodate maximum flow rates as specified by manufacturer guidelines. Whether it's installed between directional valves and subplates for main flow limitation or between pilot control valves and main valves for switching time adjustment, the Bosch Rexroth Z2FS10A7-3X/S2V offers reliable performance for sophisticated hydraulic applications requiring meter-in or meter-out throttling capabilities.
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.
