The 304 SS Ball Valve is a one-piece stainless steel ball valve. The body is a CF8 casting, the ball and stem are 304/316, and the seats mix PTFE with RPTFE. The outside is polished. A quarter turn of the handle opens or closes the bore. We rate the sizes up to 2" at 1000 psi and the larger ones at 800 psi, so the same casting wall covers the whole range without extra weight.

Wall thickness follows casting approval rules rather than guesswork
