The operation is simple. The valve manages fluid flow by rotating a circular disc within the pipe bore.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So, <a href=\"https:\/\/www.xintaivalves.com\/kk\/butterfly-valve-collection\/\" target=\"_blank\" rel=\"noreferrer noopener\">how does a butterfly valve work<\/a> in a real-world application?&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When an operator turns the stem 90 degrees, the disc rotates to a perpendicular position to block the flow.
