Product Description

Rexroth Z2FS6A2-4X/1QV R900581526

The Rexroth Z2FS6A2-4X/1QV (R900581526) is a high-performance dual throttle check valve designed for sandwich plate mounting according to ISO 4401-03-02-0-05 standards (NG6 / CETOP 03). This valve is engineered to precisely control the flow rate in hydraulic systems by providing meter-in throttling for both actuator ports A and B. It features two symmetrically arranged throttle check valves that limit flow in one direction via adjustable throttle spools with hexagon and protective cap, while allowing free, unrestricted flow in the opposite direction. Constructed with FKM seals, the Z2FS6A2-4X/1QV ensures reliable operation across a wide range of temperatures and with various hydraulic fluids, making it suitable for diverse industrial applications requiring accurate flow regulation.
