HYDRAULIC SERVO VALVES – S12 PRO
Hydraulic Servo Valves – S12 Pro
Compact Power. Proven Reliability.
The Domin S12 Pro is the next evolution in high-performance, high-flow hydraulic valves. It builds on the proven reliability of the S6 Pro, which is now used as the first stage for the most advanced two-stage valve in the world.
The S12 Pro delivers unmatched performance with the same trusted dependability. Combining high flow, excellent dynamics, proven reliability, and low power consumption, the S12 Pro sets a new benchmark in demanding applications.
With dimensions of 13.25 in (377 mm) in length and 6.9 in (177 mm) in height, the S12 Pro is thoughtfully designed with all components fully enclosed, eliminating exposed wires or sensors. This user-focused design element ensures not only a clean, sleek appearance, but also easier handling and installation.
This combination of performance and compact design makes the S12 Pro ideal for applications in industrial manufacturing, test simulation, and the energy sector.
