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.
Lowest Cost Stainless Ball Valve: One-piece construction reduces machining and assembly time — savings passed to you.
100% Factory Air Tested: Each valve tested at 6 bar (air under water) — no bubbles.
Threads Per Your Standard: NPT (ANSI) or BSP (ISO/BS) — we match your pipe thread.
Locking Handle Option: Padlockable handle for safety lockout/tagout (LOTO).
Quick Stock: All sizes from 1/4″ to 2″ available for same-day shipment.
