The Jamesbury Value-Line Series 3 three-piece ball valve offers exceptional economy and proven performance. 

These valves are available in either threaded or socket-weld configuration. 

The large port size provides high flow while minimizing pressure drop.

The stainless body caps of the 3-series socket weld valves are furnished with 316L (A351-CF3M) as standard. Seat materials are PTFE and filled PTFE which allow these valves to handle the vast majority of commonly encountered chemicals up to the full body rating, and steam to psi: 250 (kPa: 1,700, bar: 17) (saturated). Stainless-steel fasteners are standard.
