Hard to answer this, since there are many types of ball valves for just as many applications. I mean, you have sweat, and IPS valves for starters, then you have ones with different pressure ratings. Also are you running steam though the valve? Gas? Oxygen? The price on a 1" standard ball valve non-full port is $22.00 and can go as high (according to my pricing book) as $120.00 for a 1" 3-PC full port 150# SWP - 600# WOG So it all depends on the job what kind of ball valve I would use.
