Two piece 1/2 Female N.P.T 304 SS ball valve. The two piece is not designed to be disassembled for cleaning. Although it can be soaked by submerging in PBW or unscented Oxy Clean and closing the valve trapping cleaner inside the valve. After 5 or 10 minutes exercise the valve by opening and closing still submerged. Also it is good to exercise the valve when rinsing before and after use.
