I installed a new pipe system, i've written to @hot_rod
before. We were discussing flow rates and pressure drops.
I had installed tamas zmix 4-way mixing valves. They are cheap and plastic, and one of them just broke! (Now i know why they were delisted from SH).
Anyways, I am doing Tekmar controls and I went ahead and bought Tekmar 3-way replacements.
My question is about Cv. I understand that the larger the cv the larger the valve opening, and the more fluid that can pass through it. The tekmar valve has a Cv of 14.
The existing 4-way valve had a Cv of ~4.
What should I expect from this? It seems like this will be less of a flow restriction, but will it mix better? how does Cv relate to mix temperature?
