Our revolutionary Twin-power technology operates with two coils. The Dimensions [mm] (see datasheet for further Details)
innovative drive concept is combined with the proven rocker principle.
The integrated power reduction decreases the energy consumption by
75% and has the same features as a traditional 22 mm unit. In combina-
tion with other design features the heat transfer into the medium can be
reduced to a minimum.

In the design of the 6626, the main benefits lie in its excellent cleanability
and a high reliability. By using high performance materials the 6626 suits
the handling of aggressive medium perfectly. The valve is available in a C
2/2-way and 3/2-way version.
