Milwaukee Valve Company
April 29, 2005
The company's butterfly valves feature a machined seat with multiple concentric sealing edges to provide bubble-tight shut off and are available in sizes ranging from 21/2 to 24 in. for class 150 ANSI ratings and 21/2 to 16 in. for Class 300. Matching tapers between the disc and seat use flow-stream pressure to maximize sealing capacity.
