Are you using a special orifice?
The hydrogom I had from Jeroen runs a 0.009mm orifice.

0.8ltr/min flow on a 0.009 orifice means an IP of 13.9 (rounded).
At 19 bar (assuming no IP creep that is designed into the Draeger valves) means a flow of a nads over 1ltr/min.
To get a flow of 0.8 from an IP of 19 bar you need a 0.0077mm orifice.

Hi, i can´t tell what size my orifice actually is but it delivers 0,8 ltr./min at 19 bar.
I know for sure it´s smaller than the standard orifice coming with the hydrogom valve.
So propably you are right with the size you mentioned.

Regarding creeping IP see my other reply.
