Changes to Danfoss ASV, MSV, USV and MTCV Valves

To optimize production of ASV, MSV and USV valve type at Danfoss Trata, a change has been
implemented in production.

In the future the date marking and the flow direction arrow will be printed with ink-jet print on
the valve house side (see picture).

Old marking New marking

Affected code numbers

The change will influence following code numbers:
