The DynaFly 70 Wafer and 72 Lug Series are the work horses of industrial butterfly valves. Pre-sized and preassembled with our AP series pneumatic actuators, these valves come standard with ductile iron body and disc and abrasion-resistant Buna-N Phenolic Backed Seat for stretch resistant, tight shut-off during actuation and quick and easy field repairs. Pilot solenoids, positioners, other pneumatic accessories or other valve body and seat materials are available on request.

See our 700/722 Series for detailed butterfly valve information.
