I think the valve (Honeywell V4073A) in our heating system is knackered. The lever on the head gets stuck, and having taken the head off, I find that the valve has only about 10 degrees of turn.
Would this indicate the thing has had it? It's been in for probably a decade (maybe more). Also, I'd be grateful if someone could confirm how much turn you would expect in a normal working valve?
Many thanks.
