Industrial Valves & FastenersTwo Piece Ball Valves
Two Piece Ball Valves (also known as Split-Body Ball Valves) are one of the most widely used industrial valve configurations worldwide. Constructed from two body sections—a main body housing the ball and seat rings, and a secondary body end adapter threaded or bolted together—this design allows for a full-port orifice that minimizes friction loss and pressure drop across the pipeline.
Zeron Fastners manufactures precision Two Piece Ball Valves in both screwed (NPT/BSPT) and flanged (ANSI 150#/300#) connections. Utilizing investment cast and forged bodies in Stainless Steel (SS 304, SS 316, SS 316L), Carbon Steel (WCB), and Duplex Alloys, our 2-piece ball valves offer rugged durability, blow-out proof stems, lockable hand levers, and superior bubble-tight shutoff across water treatment, chemical refining, paper mills, and pharmaceutical lines.
