Pneumatic Tri-Offset Metal Seat Flange End Butterfly Valve

Features:1. The metal hard sealing butterfly valve adopts a three eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a sealing function that becomes tighter and tighter as it looks2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance, corrosion resistance, and long service life, regardless of low or high temperature conditions3. The sealing surface of the butterfly plate is made of hardfacing cobalt based hard alloy, which is wear-resistant and has a long service life4. The large-sized butterfly plate adopts a quilted frame structure, with high strength, large flow area, and low flow resistance5. The metal hard sealing butterfly valve has a bidirectional sealing function, which is not limited by the flow direction of the medium or the influence of spatial position during installation. It can be installed in any direction6. The drive device can be installed in multiple workstations (rotating 90 ° or 180 °), making it easy for users to use. Product typeSwitch valveProductdescriptionTriple Eccentric Butterfly ValveModelD343H/X/WSizeNPS 2"~72"(DN50~DN1800)Operating temperature -196ºC~593ºCOperating pressureCLASS 150~900 (PN20~PN150)MaterialA216 WCB,WCC; A217 WC6,WC9,C5,C12,C12A,CA15; A351 CF8,CF8M,CF3,CF3M,CF8C,CN3MN,CK3MCUN,CN7M; A352 LCB,LCC;A494 CW-6MC,CU5MCuC,M35-1;A890 4A(CD3MN),5A(CE3MN),6A(CD3MWCuN); ASME B 148 C95800,C95500 .etcstandardAPI 609,AWWA C504,ASME B16.34Face to faceASME B16.10Connecting endASME B16.5,ASME B16.47,ASME B16.25Test standardAPI 598,ISO 5208Operationhandwheel , worm wheelwheel,electric , pneumaticApplication fieldswater works, power plant, steel smelting, chemical industry, environmental protection system, apply to adjust the flow. Other remark 1small size, portability, easily to be repaired. Other remark 2Triple eccentric structure design, sealing face will leave when it open, it prevents mechanical wear, increase of service life.  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
