About Butterfly Valves

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.
