Rexroth Type Z2FS Series Twin Throttle Valve | Z2FSK6 Z2FS6-2-4X | Double Acting Flow Control

Z2FS Series Sandwich Plate Twin Throttle Check Valves

Product Overview: The Z2FS Series Twin Throttle Check Valve is a vital component for regulating the movement speed of actuators in hydraulic systems. Utilizing a compact sandwich plate design that complies with ISO 4401 mounting standards, it is installed directly beneath the directional valve to provide independent and precise speed control for both Port A and Port B.

This category includes the standard and compact series, featuring models such as Z2FS6-2-4X/2Q, Z2FSK6-2-10/2Q, and Z2FS6-40B. The valve functions by adjusting the throttle cross-section via screws, controlling flow in one direction while allowing free reverse flow through the integrated check valve.

Key Technical Advantages:

• Independent Dual-Port Regulation: Allows separate settings for “meter-in” or “meter-out” flow control for both A and B ports within a single valve body.

• Space-Saving Sandwich Design: Eliminates additional piping, significantly reducing the overall footprint of the hydraulic power unit and minimizing potential leak points.

• High Linear Precision: The adjustment mechanism provides stable, micro-fine flow control with high repeatability.

• Industrial Durability: Rated for operating pressures up to 31.5 MPa (4500 PSI), designed for heavy-duty, continuous industrial duty cycles.
