Butterfly valves materials can be UPVC, ABS, FRPP (Polypropylene), PPH, CPVC, PVDF, Cast Iron, Stainless Steel.
Butterfly valves are a common valve type used in large diameter pipes.
They are typically used for basic on/off service, but can also be effectively used to throttle flow.
They are operated with a simple 90 degree turn (quarter-turn) of a disc shaped obstructor.
This disc has a slim profile around which flow passes when parallel to flow, but stops the flow in the when rotated 90 degrees to fill the entire opening of the valve.
