Advancing the MD series to the MDS series

Jun 11,2026
HAFNER series development: MD series becomes MDS series

For more than two decades, our MD series with the MA16 solenoid system has stood for reliability and quality. In order to further expand our product portfolio and to offer you even more options and customized solutions in the future, we are evolving the existing MD series into the new MDS series.

As part of this development, the previous MA16 magnet will no longer be used. Instead, a new solenoid system from a renowned solenoid supplier will be implemented.

Due to this technical change, the valve terminals will also be adapted. Please note that the existing MD valves and the new MDS valves are not interchangeable on valve terminals.

Of course, we will continue to ensure long-term availability and will stock suitable spare parts for the existing MD series for at least five years.
