4" Two Piece Full Port Heavy Duty Ball Valve – 316 Stainless Steel

The 4" two piece full port heavy duty ball valve is designed for threaded piping systems requiring increased durability, reliable shut-off performance, and unrestricted flow in demanding industrial and process applications. Its reinforced heavy duty body construction provides improved strength, increased operating leverage, and long-term durability compared to standard two-piece ball valves.

Manufactured from 316 stainless steel, this valve provides enhanced corrosion resistance for applications involving moisture, chemicals, washdown conditions, and corrosive operating environments. The full port (full bore) design maintains maximum flow capacity with minimal pressure drop, while female NPT threaded ends allow straightforward installation into standard 4" piping systems.

Rated to 1000 WOG, this threaded heavy duty ball valve features PTFE seats and seals, a blow-out proof stem, and an extended quarter-turn lever handle with locking mechanism for reliable shut-off performance and increased operating leverage. Common applications include industrial process systems, chemical handling systems, utility piping, washdown systems, bulk fluid transfer systems, and demanding industrial fluid handling installations.
