Multivalve coil

[ElGrigon]

Hello,

I have an issue every half a year that may LPG tank multivalve fails.

A coil is 12V 11W and when operating it gets very hot to touch.

Since a few days ago happend again and I replaced it with a new one, I put the old one on the bench to test.
It still works but here are some pictures of the results.
What are your thoughts?

This was in first 10min. Later on the temp. raised to 145•C

And are you sure it's supposed to operate at 12v, and not maybe reduced down ?

That seems an extreme temperature to be running at, no way can it be normal.

I wonder if it uses the rest of the valve as a heat sink...? Or is supposed to.

I had a thaught perhaps it is expected to be running a fluid and that the fluid will draw and move the heat away

Have you reached out to any LPG places ?
