| P Valves - could someone explain the diff?
Hi,
Probably being thick here but hey what's new ?
Can someone explain (in terms for a muppet) what the diff is between a "balanced" and "un-balanced" P-valve. The pros and cons would good too.
Reason for asking is I need one fitting for something I'm doing later in the year and need to decide which I need / want.
Ta.
