It is the most chemically critical component in corrosive service applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common seat materials and their key properties include the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>EPDM: <\/strong>suitable for water, steam, and mild chemical service up to 250\u00b0F.<\/li>\n\n\n\n<li><strong>NBR (Nitrile): <\/strong>compatible with oils and hydrocarbons, rated to 180\u00b0F.<\/li>\n\n\n\n<li><strong>PTFE \/ RTFE: <\/strong>broad chemical compatibility, rated from -40\u00b0F to 400\u00b0F, most common for chemical service.<\/li>\n\n\n\n<li><strong>PFA lining: <\/strong>a <strong>PFA-lined butterfly valve for chemical processing<\/strong> fully encapsulates the body and stem. This isolates all metal parts from corrosive or ultra-pure media, eliminating the need for expensive alloy bodies.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">High-performance designs use line-energized seats, where pipeline pressure increases the sealing force.

The 90-degree or quarter-turn action easily operates the valve to an open\/close position.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the closed position, the disc sits perpendicular to the flow direction. It blocks the entire pipe bore and prevents fluid passage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A 90-degree rotation moves the disc parallel to the flow path. This creates an annular opening around the disc edge, allowing fluid through with minimal resistance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Az aerodinamikus t\u00e1rcsaprofil cs\u00f6kkenti a turbulenci\u00e1t \u00e9s a nyom\u00e1ses\u00e9st.
