This troubled me too and I found it unexplainable until I thought that the
valve, valve stem and metal were probably hot from having been previously
heated by heater core. If their temperature had'nt dropped below 100C there
could be considerable flahing to steam upon exit of water through the valve.

Here my Analysis:
At the end, when the water input valve is opened, then a mixture out of water
and steam comes out with remarkable pressure.
Now, how can we have pressure when the steam outlet is still open?
Answer: The steam outlet is not open. Probably there is a pressure reduction
valve in the oulet. This opens at 1-2 bar pressure and it closes when the
pressure sinks.
This means inside the ecat is always 1-2 bar overpressure.
Saturated steam temperatures versus pressure tabulated:
(This is the over-pressure that is more than air pressure)
1 bar -> 120.2°
1.5 bar -> 127.4°
2.0 bar -> 133.5°
2.5 bar -> 138.9°
Now this explains why water and steam come out. Water comes out and it has a
temperature of 120°.
Wenn it flows out it will vaporize partially and produce steam.
This also explains the water output flow at the steam hose:
The steam inside of the ecat has a pressure between 1 and 2 bar and a
temperature between 120 and 133 centigrade.
When the steam passes the pressure reduction valve then it will expand to air
(over) pressure of 0 bar. To do this, work must be done and the steam will cool
down to 100° and partially condensate. This explains the output water flow at
the steam outlet.
So far my qualitative steam & temperature & pressure analysis.
There is one thing that irritated me. When they show the e-cat in
self-sustained mode, then I cannot hear the pump anymore. Did they stop the
pump and why?
Best,
Peter
