Butterfly Valve Body
A Butterfly Valve Body is a pressure vessel that controls flow through a pipe by use of a single disc mounted on a central shaft which creates a variable orifice. Butterfly valves generally have bodies that fit between two pipe flanges, the most common being lug and wafer body design. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. The offered Butterfly Valve Body is made for commercial uses. They have a relatively simple construction. The main components of a butterfly valve are the body, disc, stem and seat.
