Description
The Domin S6 Pro combines exceptional power density with proven reliability, thereby setting the benchmark for servo valves in industrial manufacturing, test benches and demanding automation systems. It offers the size, mass and dynamics of the best two-stage valves – combined with the simplicity and low leakage of direct-drive technology. With its standardised NG06 connection pattern, it can be used directly as a high-performance replacement for conventional two-stage NG06 valves; an NG06-to-S04 adapter is available as an option. Users benefit from consistent performance, extended service life and reduced downtime. Typical applications include highly dynamic injection moulding machines, test bench technology, machine tools, materials testing systems and industrial automation with demanding control requirements.
