I just wanted to clear up some gas valve terminology.
What does it mean when they call a valve Redundant?
It means it has two valve inside it. In case one fails.
41530 is right and correct too.
Believe none of what you hear and half of what you see.
so it just means there is a pilot valve and a main valve?
When there is a pilot valve and main valve in the same valve body, it is called 'combination'. 'Redundant' is a fail-safe feature. There can be a 'Redundant combination' gas valve.
