Rexroth Type Z2FS Valve | Z2FS10-5-3X Z2FS16-8-31 | Twin Throttle Check Valve

Rexroth Type Z2FS10 & Z2FS16 Series Twin Throttle Check Valves

Product Overview: The Z2FS Series is a high-performance, stackable twin throttle check valve designed to regulate the main or pilot flow of hydraulic actuators (cylinders or motors). Adhering to ISO 4401 standards, this series covers Size 10 (NG10) and Size 16 (NG16) nominal sizes. Its modular design allows independent speed control for both A and B ports without additional piping, enabling flexible switching between meter-in and meter-out flow control.

This selection features premium configurations: the high-performance Z2FS10-5-3X/V and the high-flow, high-pressure Z2FS16-8-31/S.

Key Technical Advantages:

• Symmetrical Modular Design: The valve body is symmetrical, allowing a logical switch between meter-in and meter-out control simply by flipping the valve horizontally during installation.

• Precision Throttle Adjustment: Equipped with adjustment screws featuring lock nuts or optional handwheels, ensuring smooth and accurate velocity control of actuators.

• High-Temperature Compatibility (V-Series): Optional Viton (FKM) seals ensure zero leakage and long service life in high-temperature environments or with specialized synthetic fluids.

• Space-Saving Integration: By stacking directly beneath the directional valve, the total footprint of the hydraulic manifold is minimized while reducing potential leakage paths.
