4" 3 Piece Ball Valve – Inline Serviceable Full Port Design

The 4" three piece full port ball valve is designed for general industrial piping systems requiring reliable shut-off and inline service capability. Its split-body construction allows the center section to be removed for inspection or seat replacement while the threaded end connections remain installed in the pipeline.

Manufactured from 316 stainless steel, this 3 piece ball valve provides corrosion resistance and durability in industrial environments. The full port internal bore maintains maximum flow capacity with minimal pressure drop.

Rated to 1000 WOG, this threaded valve installs easily into standard NPT piping systems and delivers dependable sealing performance through PTFE seats and a blowout-proof stem design.
