This concentric wafer butterfly valve features a ductile iron body, CF8 stainless steel disc, and PTFE seat. The PTFE seat provides outstanding chemical resistance, a wide temperature range (-35℃to +200℃), and low friction operation. The concentric design ensures symmetric sealing, low torque, and bi-directional flow capability. Available DN50-DN600, PN10/PN16/Class 150. Suitable for chemical dosing, water treatment, food processing, and high-purity applications. Disc and seat materials are fully customizable for more aggressive service conditions. Manufactured by Tianjin Worlds Valve Co., Ltd., an ISO 9001 certified OEM supplier.

This wafer butterfly valve from Tianjin Worlds Valve Co., Ltd. combines a CF8 (ASTM A351 Grade CF8) stainless steel disc with an NBR rubber seat, built into a ductile iron (GGG40) wafer body. The standard NBR seat performs well in oil, fuel, aliphatic hydrocarbon, and mild chemical media. Beyond this baseline configuration, all major components are fully customizable: disc materials include CF8, CF8M, Duplex 2205, Super Duplex 2507, and Aluminum Bronze; seat materials include EPDM, Viton (FKM), and PTFE. The product covers DN50–DN3000, fits PN10/PN16/Class 150 pipelines, and conforms to ISO 5752 face-to-face dimensions. Suitable for water treatment, oil handling, HVAC, food processing, and general industrial services.

This product describes a lug butterfly valve featuring a CF8M (AISI 316) stainless steel body and disc, operated by a manual hand lever. The lug design allows dead-end-service – the valve can be installed at pipeline ends without a downstream flange. Available with replaceable seats (EPDM, NBR, FKM, PTFE) for various media. Sizes DN50-DN2000 with customizable pressure ratings (PN10, PN16, Class 150) and flange standards (EN 1092, ANSI B16.5, etc.). Suitable for seawater, chemical processing, high‑purity water, and corrosive industrial applications. Fully customizable as an OEM product from Tianjin Worlds Valve Co., Ltd.
