I've been installing some new mainlines to my wet/dry, and have been wondering why no one has come up with a barbed 3/4" or 1" ball valve. I've seen many bushes using all stainless Y's and Tee's fitting, and then using a plastic 3/4" ball valve with plastic NPT to 3/4" adapter. What's the point of spending all that money to prevent restriction, and then installing a isolation ball valve that restricts the CFM flow? A barbed ball valve would reduce the number fittings and leaks on many manifolds.
