Product Overview
The ATOS SKQ-02/3 10S is a modular, sandwich-style flow control valve engineered by Atos (Atos S.p.A.) for precise regulation of actuator speed within industrial hydraulic systems. Operating on a pressure-compensated, two-way flow control principle, the valve maintains a constant set flow rate independent of load and pressure fluctuations, ensuring stable and repeatable motion control. Designed to ISO 4401 / CETOP 03 (NG6) interface standards, the SKQ-02/3 10S mounts directly between a directional valve and its subplate, eliminating the need for additional piping and simplifying system integration. The “3” designation denotes a 3-way flow control configuration, while the “10S” suffix identifies the specific pressure and flow range calibration. This modular valve is a direct-fit, drop-in replacement for OEM Atos assemblies and is widely deployed in demanding industrial circuits where accurate velocity control is critical.
