3 Piece Stainless Steel Ball Valve, Full Port Design, ISO Mounting Pad, Threaded End Connections
3-piece Ball Valve is a quarter-turn valve that uses a hollow, perforated, and pivoting ball to control flow through it. It is open when the ball’s hole is in line with the flow. It closes when it is pivoted 90 degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve’s status.
Pressure: 1000PS/1000WOG
