Overview

3-PIECE STAINLESS STEEL BALL VALVES are engineered for maximum serviceability, durability, and process control in industrial stainless steel piping systems. Their swing-out center section allows easy inline maintenance, seat replacement, and cleaning without removing the valve body from the piping system—making them the preferred choice for high-cycle, sanitary, and corrosive service applications.

Ace Stainless supplies 3-piece ball valves in full-port configurations with ISO direct-mount pads, PTFE/RPTFE/TFM/PEEK seats, blowout-proof stems, and precision-machined stainless bodies. Available in threaded, socket-weld, butt-weld, and Tri-Clamp sanitary connections.

Ideal for OEMs, process engineers, sanitary system builders, and facilities requiring long-term reliability and maintainability.
