The butterfly valve is a rotary valve in which a disk-shaped seating element is rotated 90° to open or close the flow passage. Can be left partially open or closed for flow throttling. Butterfly valves cannot be used where a non obstructed full opening is needed. Needs to be installed with flanges. No need for gaskets since they already have a rubber seal.
Features:
Excellent corrosion resistance
Lever handle can lock in 10 positions for throttle control
Does not require flange gaskets thanks to EPDM seat
