The Danfoss VDHT 2E is a small valve for minor low rates up to 2 litres per minute (0.52 GPM).
It is a direct operated type of valve with one NO and NC armature.
The VDHT 2E requires 2 coils activated by a common signal (ie. 24 V AC). It is suitable for systems with many zones with few nozzles and is a very cost effective solution.
The VDHT 15E is a medium size single inline valve for low rates up to 15 litres per minute (4 gpm to the zone). It is based on the latest valve technology, comprising a piston type NC valve and a NO pilot stage in one housing. The NO part has a relative small orifice, so it cannot drain a big volume very fast.
It covers a very wide low range already starting from 1 litre per minute (0.26 gpm) and is the ideal solution instead of using 2 separate valves (1 NC and 1 NO). The VDHT 15E requires 2 solenoids activated by a common signal (i.e. 24 V AC).
