I had no idea what a 'globe valve' was .. wikipedia has it ...
what I
had called 'jumper valves' as that is the bit I have replaced many
times.
Glad to learn another way to name them too
Jumper valve sounds like the domestic name for globe it seems
Think it is more to do with naming the sealing washer? It "jumps"
back to prevent back flow.
And defiantly domestic use.
Do you mean a "one-way" or "check" valve?
https://en.wikipedia.org/wiki/Check_valve
No. A check valve only does one thing, stops back flow.
A 'globe valve' controls the rate of flow anywhere from off to on, if
fitted with a jumper valve it also stops back flow.
