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.

This lug butterfly valve features a C95400 aluminum bronze disc, a PTFE seat, a split body construction, and a hand lever. The aluminum bronze disc provides exceptional corrosion resistance in seawater, brackish water, and aggressive chemical environments. The PTFE seat offers chemical inertness, low friction, and a temperature range of approximately -35°C to +200°C. The two-piece body allows easy maintenance without pipeline removal. The lug design enables dead-end service at full rated pressure. Available DN50-DN1200, PN10/PN16/Class 150. Suitable for marine, chemical, desalination, and industrial applications. Manufactured by Tianjin Worlds Valve Co., Ltd., an ISO 9001 certified OEM supplier.
