This article highlights the benefits of using UNS C95400 aluminum bronze discs in dual plate wafer check valves, particularly for seawater and corrosive applications. It explains how the aluminum bronze material resists chloride attack and marine bio-fouling, while the ductile iron (DI) body provides structural strength at an economical cost. Paired with an EPDM seat and stainless steel springs, this configuration ensures rapid, reliable backflow prevention. The article is backed by Tianjin Worlds Valve's OEM/ODM manufacturing capabilities and LRQA ISO 9001 certifications.
This technical article compares EPDM, NBR, and PTFE valve seat materials for industrial applications. It outlines the advantages of elastomers (EPDM for water, NBR for oils) and the necessity of PTFE for aggressive chemicals and temperatures up to 200°C. Crucially, it clarifies the engineering difference between a "PTFE seated valve" and a "PTFE fully lined valve." The guide includes a material selection matrix and concludes with Tianjin Worlds Valve's manufacturing capabilities and CE/PED, WRAS, and ACS certifications.
This article introduces an 8-inch PTFE lined butterfly valve with a double flanged, two-piece split body design. The valve features a fully PTFE lined body bore and flange faces, a PTFE encapsulated stainless steel disc, and a PTFE seat—providing complete metal isolation and excellent corrosion resistance for chemical, pharmaceutical, petrochemical, and seawater applications. The split body allows in-line maintenance and field-replaceable PTFE components. 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.
