Butterfly
A Butterfly Valve is a form of a quarter-turn valve which uses a metal disk for the closing mechanism. The disk is positioned in the center of the pipe and is open when the surface of the disc is parallel to the flow, closed when the disc is perpendicular to the flow. All of the Butterfly Valves we stock are designed to be connected between two flanges.
- Lug type Butterfly Valves connect between two flanges and have threaded inserts so that each flange can be bolted to the valve.
- Wafer type Butterfly Valves are sandwiched between two flanges, but the valve is not bolted to either flange.
- Butterfly Valves are stocked in sizes from 2 to 12 inches.
- All have a BUNA seat and Nickel plated disc..
