Pneumatic Butterfly Valves
Butterfly Valves Are The Best Choice For Many Applications
Butterfly valves have a wide variety of uses for high flow applications. They are the best solution where cost is a factor. They are available with pneumatic or electric actuators, from 2'' to 24'', 2-way, 3-way, for steam, chilled or hot water.
