Hi Jovannie,

No problem at all. Unfortunately not, there is no way of manually altering the K values - the only way to work around this would be to modify the bend/tee type by using Fix Bend/Tee option as below:

The K value details used in the software listed here may also be of some assistance to you.

Hi Shane,

Thanks for this.

I just want to clarify regarding this specific point.

Is there no other way for us to use the data (using Hevacomp Netsys software) for K values as described in CIBSE Guide C 2007 and not in CIBSE Guide C 2001?

Hi Jovannie, the user defined fitting will be in addition to the bend, it will not override it. Unfortunately there is no way of manually editing the K-values in the software for the automatic bends tees and fittings.
