What Is a Three Piece Ball Valve?
A three piece ball valve uses two end caps and one center body. This structure allows the center body to be removed for cleaning, inspection or seat replacement without dismantling the full pipeline connection.
Compared with one piece or two piece ball valves, a 3 piece ball valve is more suitable for process lines that require regular maintenance, sanitary cleaning, internal inspection or quick replacement of soft sealing components.
ZONCIC works as a three piece ball valve manufacturer for distributors, EPC contractors, OEM equipment builders and industrial end users who need dependable shut-off valves with technical documentation and export packing.

Easy Maintenance
The center body can be removed more conveniently, helping reduce downtime for cleaning, inspection and internal component replacement.
Flexible Connections
Threaded, socket weld, butt weld and flanged ends are available according to installation layout, pressure rating and project standard.
Reliable Shut-Off
Precision-machined balls, stable seats and controlled assembly support dependable sealing in industrial pipeline service.
