Full Port with ANSI 150# or 300# Flange Connections (1/2" to 6")
Manual and Actuated Flanged 3-way ball Valves



One Piece Stem/Ball Trunnion Support Design provides for precision operation and positioning of the ball. This precise ball positioning is often not possible in more common multi-piece stem ball design. This also allows all sides to be used as an inlet or block port without leakage.
