Default Re: Difference between HB and GW manual valves

The pics are not what I'd consider a good guide if wanting to make minute comparisons on flow rate. Valve stem has nothing to do with the flow. Both valves have 1/2" NPT fittings and the inside architecture of the valve was undoubtedly copied from the Graham White.

Would you have a quality difference? Yes, absolutely
Would there be any difference in flow rate that you could pick up with your ears by listening to a bellowing train horn? Absolutely not!

If quality and reliability is your main concern, then spend the extra coin on a genuine GW, but if all you're worried about is the possibility of losing out on volume due to flow rate, you're barking up the wrong tree.
