\n[1] Structure Introduction
\nLug type butterfly valve, also known as branch type butterfly valve, adopts a triple eccentric structure in the American standard lug type butterfly valve. The valve seat is sealed with a metal multi-level hard sealing structure, usually a interlayer of metal and graphite, such as 304+graphite and 316+graphite. This hard seal can also be made into a single layer soft seal PTFE, RPTFE, PPL, EPDM, NBR and other triple eccentric butterfly valves. Features:
\n1. Short structural size, small volume, light weight, and operational aspects
\nAdopting a full axis mechanism, the butterfly plate has high strength and a large flow area
\n3. Unique triple eccentric design reduces seal friction loss and greatly extends service life
\n4. Metal hard sealing is resistant to high temperature, low temperature, high pressure, and has a wide range of applications
\n(II) Relevant standards for American standard butterfly valves
\nDesign and Manufacturing: API 609
\nStructure length: API 609
\nConnecting flange: ASME B16.5
\nInspection and pressure test: API 598<\/p>\n","protected":false},"excerpt":{"rendered":"
