I asked a similar question here.....

I went with the 29psi version. It's been excellent! Amazon didn't have it, at least not at the price I paid.

Edited to add: The CF valve coupled with the Teejet was awesome. I had no idea spraying could be like that. Perfect, even, and predictable flow and patterning. I'll never spray without that setup again.

I have the standard 4 Gal Chapin 4 gallon backpack sprayer (Pump type), I was thinking about getting a CF vale to make the flow constant and aid in applying solutions evenly. Should I get the 21 PSI or the 14.5 PSI valve?

I would probably opt for the 21 psi Chapin CF valve or the 29 psi Chapin CF valve for a Chapin manual pump backpack sprayer. I don't think you would have any trouble maintaining those system pressures.
