Description
FLUIDCHEM’s Double Flanged Butterfly Valves have double flanged body pattern which ensures precise installation in pipeline, and can be used as an end to the line valve if required. The unique feature of this valve, is its adaptability for lined pipes, due to negligible disc protrusion beyond the body laying length. These are available in cast as well as fully fabricated design.
Purpose
Butterfly valve is a flow regulating disc valve, rotary valves in which a disc – shaped closure member is rotated through 90º, or about to open or close the flow passage. The main function of these valves is to control the flow of liquids through a section of pipe.
