 DynaFly
Series 
340/342 Series Butterfly Valve with Pneumatic Actuator
'The DYNAFLY SERIES' offers an excellent option for the majority of automated applications. The packaged butterfly valve and actuator
unit is pre-sized and pre-assembled taking the guesswork out of sizing and assembly. The valve has a built-in platform mounting
(eliminating brackets) giving a more compact assembly and true alignment. Available in lug or wafer style butterfly valves perfect
for general industrial service, HVAC/ATC, or chemical/petrochemical processing.
 The
DynaFly 340/342 Series valve has a ductile iron body with a Nylon 11 coated disc. Nylon 11, an FDA approved vegetable-based thermoplastic,
is resistant to mold and fungus. Nylon 11 coating provides a high level of corrosion resistance, a durable surface, and low coefficient
of friction. Valve is directly mounted to an AP series pneumatic actuator. Available in double acting and spring to close or spring
to open. Sized for 80psi of plant air and 175 media psid clean water, air, or light oil applications. For dirty or severe applications,
please call customer service.
