K factors

The K factors have all been determined in the following reference
conditions:
medium = water, water and ambient temperatures 20 °C, min. upstream
and downstream distances respected, appropriate pipe dimensions
Two versions of the S012 in DN15 and DN20 exist, having
different K factors.
Only version 2, identified by the "v2" marking, is available
from March 2012. The "v2" marking can be found:
• on the bottom of the DN15 or DN20 fitting in plastic:
• on the side of the DN15 or DN20 fitting in metal:
