Buy DOMIN proportional valves from a premium supplier
DOMIN’s servo and servo-proportional valves set a new benchmark in electro-hydraulic control technology. Through the consistent use of direct-drive technology with integrated on-board electronics and spool position feedback, they combine the dynamics and precision of classic two-stage servo valves with the simplicity, robustness and low leakage of modern direct-drive valves – without the need for an external amplifier. As an authorised distributor, we offer you the complete DOMIN range, from ISO S01 size up to NG16, individually configured to your requirements.

Overview of DOMIN servo and proportional valves
DOMIN valves are used in particularly demanding applications where precision, range and stability have a direct impact on safety, throughput and life-cycle costs. Typical areas of application include injection moulding machines, presses, test benches, materials testing equipment, machine tools, robotics, motor sport, aerospace and highly dynamic industrial automation.
All DOMIN Pro valves share the same tried-and-tested platform architecture:
- On-board electronics with slider position feedback – no external amplifier required
- Standardised ISO connection diagrams – direct 1:1 replacement of conventional servo valves
- Low power consumption, typically less than 5 W – energy-efficient in continuous operation
- High tolerance to contamination due to high chip shear forces – extended service life
- Flexible configuration – control signals, connectors, seals and valve characteristics can be selected individually
- Maximum operating pressure 350 bar (P, A, B), protection class IP65
In conjunction with our control electronics and our hydraulic control blocks, we provide you with complete control engineering solutions from a single source.
