I acquired a gas regulator a while back that had failed.. first symptoms were a reduced flow and then it just shut down..
Its the model fitted with the secumotion and a reset button..
Ive opened it up and they appear fairly basic so was wondering how it failed..
Nothing obviously wrong with the mechanism ..
The only thing that is apparent is the inlet or 1st stage reduction seems to be blocked when compared to another regulator... ie blowing air through it...
Not that scientific i know
Im assuming the rubber valve seat must have swollen (and blocked the flow ) after been contaminated with the residue from the gas , but there wasnt a lot of that present..
If anyone knows of the supposed reason for them failing id be interested..
Like i say there doesnt appear to be a lot to go wrong in them..
Again some pictures..
Ist stage side showing the residue present..
2nd stage side..
And another view of 2nd stage mechanism
