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:

Delivery
The change has already been implemented in the production at Danfoss Trata, and future
deliveries to CDC will be with the new marking. Deliveries of valves with new marking will take
place as soon as old stock at CDC has been used up.
