Floating Type 3 Piece Ball Valve
1. Product overview
Forged steel 3 piece ball valve with mounting pad, floating type, side entry, full bore(FB) or reduced bore(RB), NPT or BSPT end.
Metals Valve manufactures small sizes(2″ and below) forged steel floating type 3 piece ball valves covering pressure ratings of 800LB, 1500LB and 2500LB. These lever operated valves are often furnished with screwed ends. The bolted body is constructed by 3 separate body parts. The central body can be easily removed without disturbing the end connections hence it is cost effective for maintenance. See the technical specifications for full port and reduced port forged steel three-piece ball valves.
