This article introduces a through-hole wafer butterfly valve featuring a split body design, PTFE seat, polished stainless steel disc, and ductile iron body. The through-hole mounting eliminates threaded lugs, allowing bolts to pass through the body and flanges for secure, cost-effective installation. The split body construction enables in-line maintenance and field-replaceable PTFE seats, while the PTFE seat provides superior chemical resistance for aggressive media. Ideal for chemical processing, pharmaceutical, petrochemical, water treatment, and desalination applications. As an LRQA-certified ISO 9001:2015 OEM/ODM manufacturer with over 15 years of export experience, Tianjin Worlds Valve Co., Ltd. offers fully customizable solutions to meet specific project requirements.
