Hello; I have seen a picture or two of the insides of a Speedster and it looks like the solenoids are Parker-Hanifin, is this correct? Are these of a more robust design then the average espresso machine valves? I've used them and Asco brand valves in my years in industry. This subject has come up on HB in terms of LM GS3 reliability and espresso machine reliability in general.
PS: May I post your answer on HB?
His answer (with permission) :
We have been using these Parker valves (2-way/2.5mm orifice, 3-way/1.5mm and 2-way/6mm, all with Viton gaskets, no Ruby) in our Mirage series for 10 years without ever noticing they go wrong quickly. Don't know if these are available in different levels of quality.
Sure you may,
All the best,
Could this be an answer to some problems with solenoid valves in other machines? Could Parker solenoids be retrofitted where room exists and failures have been recurring?
