Description
The Domin P10 Pro is a direct-driven, high-performance servo-proportional valve with a nominal size of NG10, designed for demanding heavy-duty applications. Thanks to its high dynamic stability and robust construction, it reliably handles high hydraulic flow rates – with a nominal flow rate of up to 160 l/min. As a drop-in replacement, it fits existing NG10 connection layouts and is designed for environments where consistently precise control under high loads is crucial. Typical areas of application include presses, energy and power station technology, and large-scale industrial automation.
Technical highlights
- Directly driven servo-proportional valve, nominal size NG10 – drop-in replacement for existing NG10 connection diagrams
