What Makes a Two Piece Ball Valve Different?
A two piece ball valve uses a body and end cap structure that provides a stronger and more serviceable design than many one piece ball valves while remaining more economical than some three piece configurations.
As a two piece ball valve manufacturer, ZONCIC supplies stainless steel, carbon steel and alloy options for buyers who need reliable sealing, quarter-turn operation, export-ready documentation and stable industrial quality.
For other body structures, review our threaded ball valve, three piece ball valve and flanged ball valve pages.
