As an experienced OEM butterfly valve supplier, we provide high-quality ductile iron wafer type butterfly valves that combine reliable performance with competitive pricing for water treatment, HVAC, industrial, and building service applications worldwide.
This article compares wafer butterfly valves with traditional gate and globe valves, focusing on installation space, operation speed, cost, and maintenance. It highlights the advantages of wafer designs – compact, lightweight, low pressure drop, and automation‑ready. Tianjin Worlds Valve Co., Ltd. is presented as a reliable OEM/ODM manufacturer offering full material customization, replaceable soft seats, and international certifications (ISO 9001, CE, UKCA, WRAS, ACS, DNV/ABS). The guide helps engineers select the right valve based on media, temperature, pressure, and frequency of operation, with practical tips on seat and body materials.
This 14” double flanged butterfly valve features a WCB body, CF8 disc, vulcanized Viton (FKM) seat, and SS304 stem, rated Class 150LB. The permanently bonded Viton seat provides excellent resistance to oils, fuels, acids, and high temperatures up to 200°C. Ideal for chemical processing, oil & gas, and high-temperature industrial applications. Manufactured by an ISO 9001 certified OEM supplier.
This article explains how wafer butterfly valves work and their key advantages: space-saving compact structure, lightweight handling, low cost, fast quarter-turn operation, good sealing, and smooth flow control. It also covers material selection and how to choose the right valve from Tianjin Worlds Valve.
A wafer butterfly valve controls flow with a simple 90° rotating disc. This article explains how it works, its main components, compact and lightweight design advantages, common applications in water treatment, HVAC, and chemical systems, plus practical tips for selecting the right seat materials and actuator options for different industrial pipelines.
This 2” double flanged butterfly valve from Tianjin Worlds Valve combines a 1.4462 super duplex disc, vulcanized EPDM seat, and ductile iron body with customizable epoxy coating (any RAL). The non-replaceable seat ensures leak-proof sealing, while the super duplex disc provides twice the strength and superior chloride resistance for seawater and chemical applications. Hand lever operated, PN10/PN16/Class 150, fully customizable. ISO 9001 certified OEM.
