The Stainless Steel One-Piece Ball Valve is the most economical stainless steel ball valve configuration. The body is machined from a single stainless steel casting (CF8 or CF8M) with integral threaded ends — there is no center body joint. The ball is inserted through the end before the seats are installed. This design minimizes parts and cost while still providing reliable shut-off for small bore lines. The floating ball design means line pressure pushes the ball against the downstream PTFE seat for bubble-tight sealing. The valve is operated with a standard lever handle that rotates 90° from fully closed to fully open. A blow-out proof stem ensures safety even under full pressure. This valve is ideal for general corrosive service where the budget is a concern.
