Rexroth Type Z2FS & Z2FSK Series Valve | Z2FSK6-2-1X/2QV Z2FS10 Z2FS22 | Twin Throttle Check

Rexroth Type Z2FS & Z2FSK Series Twin Throttle Check Valves

Product Overview: The Z2FS Series Twin Throttle Check Valve is a precision component designed to regulate the movement speed of hydraulic actuators (cylinders or motors). Featuring a standard sandwich plate design that complies with ISO 4401 mounting standards, it is installed directly beneath directional valves, significantly saving manifold space. Its primary function is to independently adjust the flow for Ports A and B, allowing for flexible switching between “meter-in” and “meter-out” control.

This series specifically includes the compact Z2FSK6 version and models with V (Viton) seals (e.g., Z2FSK6-2-1X/2QV), making it ideal for high-temperature environments and various specialized fluids. It is the premier choice for CNC machine tools, die-casting machinery, steel metallurgy, and automated production lines.

Key Technical Advantages:

• Independent Dual-Port Regulation: Controls flow for two ports independently within a single valve body, ensuring precise speed management for both extension and retraction of actuators.

• Viton Sealing (V): Equipped with high-grade FKM (Viton) seals for superior thermal resistance and chemical stability, significantly extending service life in harsh environments.

• Compact Architecture (Z2FSK): Offers a more streamlined structure compared to the standard series, perfect for space-constrained hydraulic integrated circuits.

• High-Pressure Durability: Rated for operating pressures up to 31.5 MPa (4,500 PSI), featuring adjustment screws with excellent linearity and stability.
