PNEUMATIC OPERATED PLASTIC BUTTERFLY VALVE -1268 SERIES

Plastic Butterfly Valves available in two types or styles, wafer and lug. A different installation procedure is used for each one. Wafer Style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. Wafer butterfly valves are installed between two flanges using bolts or studs and nuts. This type of installation of course, makes it impossible to disconnect just one side of the piping system from the valve. That is where the lug style valve comes in.
