Rexroth Type Z2FS & Z2FSK Series Modular Twin Throttle Check Valves

Product Overview: The Z2FS and Z2FSK Series are essential modular hydraulic components used to regulate the speed of actuators (cylinders or motors). Adhering to ISO 4401 standards, this range includes the standard Size 10 (NG10) and the space-optimized compact Z2FSK Size 6 (NG6). By stacking these valves vertically beneath a directional valve, users can independently fine-tune the meter-in or meter-out flow for both A and B ports without modifying existing system piping.

This category features the high-temperature Z2FS 10-5-34/V and specialized compact models like Z2FSK6-2-11/2KV and Z2FSK6-2-45/2QV.

Key Technical Advantages:

• Standard & Compact Flexibility: The Z2FSK series is specifically engineered for space-constrained manifolds, offering a smaller footprint while maintaining high flow limits.

• Seamless Meter-in/out Conversion: Due to the symmetrical valve body, switching between meter-in and meter-out control is achieved simply by rotating the valve 180° during installation.

• Premium Sealing (V & QV): Models with V or QV suffixes utilize Viton (FKM) seals, ensuring chemical resistance and compatibility with phosphate ester fire-resistant fluids and high-temperature environments.

• Exceptional Adjustment Linearity: Precision-ground throttle spools guarantee smooth regulation and high repeatability even at very low flow rates.
