Filter
For installations with ammonia and similar industrial installations, a lter must be mounted before AKVA 15 and AKVA 20
AKVA 10 has a built-in lter and an external lter is not necessary.
Recommended lters for AKVA 20
Dimensionsing
To obtain an expansion valve that will function correctly under dif-
ferent load conditions it is necessary to consider the following points
when the valve has to be dimensioned:
These points must be dealt with in the following sequence:
1) Evaporator capacity
2) Pressure drop across the valve
3) Correction for subcooling
4) Correction for evaporating temperature
5) Determination of valve size
6) Correctly dimensioned liquid line
