Every since I bought my boat, I have had chronic gas solenoid failures. They typically last about 18 months. This is very frustrating, because the ones I use -- Gas Solenoid Valves - VAL-12/24V-PS
-- cost about $200.
It's failed again
; as if I didn't have enough things on the List.
So in my frustration I decided to find something cheaper, and ran across these:
Which only cost 20 pounds, and are made in Germany
, and certified in all kinds of ways.
Then I noticed the operating pressure, only 500mB. My solenoid is mounted BEFORE the regulator
, so deals with the full pressure of the bottle. I don't know how much that it, but it must be a couple of bar at least.
Then I looked at the specs for my old Nereus ones: http://www.nereusalarms.co.uk/VAL-12...ion_Manual.pdf
It's only rated to 700mB!! And the manual says that it must be mounted on the low pressure side!
So much for the professional gas fitter who fitted the first one back in 2009, who replaced the first one under warranty, who inspected my system and gave me gas certificates year after year
So they haven't been failing because they're carp; they've been failing because they are being required to deal with pressure out of their specs.
So now on top of everything else I have to do, I have to reconfigure my gas system to put the solenoid on the low pressure side.
I wonder if I can find a clip on regulator
like the one I have on my Finnish gas bottle? This eliminates a hose and two connectors; surely a worthwhile simplification.

this in case anyone else is wondering why his solenoids keep failing
