It's the parts from a solenoid valve! But not as we know it!

Interesting, as Danfoss Australia we cannot get EVRA anymore, only EVRAT because it then has less stock to keep, or rationalize.
Prior to that they were normally used for things like oil return from flooded evaporator where no pressure drop was required.
Not really sure about this picture, spring in armature is missing?
We have to use them for everything for years & no apparent problems except on one occasion would not open when upstream of a Fisher modulating valve.
Years ago seat insert in diaphragm used to "work itself out" not allowing any clearance for armature lift.
