The Bosch Rexroth Z2FS6A2-4X/2Q (R900427254) is a high-performance industrial hydraulic valve designed for reliable throttling of flow to a preset value. This mechanically actuated valve, belonging to the ZFS type series, is a twin throttle check valve that features a sandwich plate design, which makes it suitable for both main or pilot flow limitation in hydraulic systems. The Z2FS6A2-4X/2Q model is characterized by its direct actuation and setscrew with lock nut for precise flow control. This valve allows for the symmetrical alignment of two throttle check valves to limit flows in one direction while enabling free return flow in the opposite direction. The adjustment of the throttle spool via the setscrew allows for fine-tuning of the throttling point. In supply throttling applications, hydraulic fluid flows through channel A and is directed by the valve seat and throttle spool to actuator A, while in return, the fluid displaces the valve seat against a spring to allow unobstructed flow back. The Z2FS6A2-4X/2Q can be installed between directional valves and subplates for main flow limitation or between pilot control valves and main valves for pilot flow limitation. It offers various adjustment types including a lockable rotary knob with scale and spindle with internal hexagon and scale. This model conforms to DIN and ISO porting patterns, making it versatile for integration into various hydraulic systems. It has been designed with a size that corresponds to CETOP D standards, maximum operating pressure capability of up to bar, and can handle maximum flows of l/min. The unit's weight and NBR seals make it robust enough for demanding applications using hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, or HFC.
