Hi there,

Danfoss has a programme called Dircalc which is for Industrial Refrigeration. This programme also selects the required components.

My question is for PM valves. There are three different ways which programme uses to select the PM valve.
1- Pressure Drop
2- Velocity
3- Size

By selecting one of the options then a valve is selected which completely differers from the other option.

In your expert opinion which one is the best and why? (if you don't mind explaining ).

Thanks in advance.
Cheers
