China DN100 Cast Iron Wafer Butterfly Valve Supplier - FTJ Valve
Welcome to FTJ Valves, your premier China DN100 cast iron wafer butterfly valve supplier. We specialize in engineering high-performance, cost-efficient, and durable flow control solutions tailored for global industrial applications. As a dedicated dn100 cast iron wafer butterfly valve supplier, we provide top-tier DN100 (4 inch) wafer-type butterfly valves designed to deliver reliable shut-off and precise regulation in water treatment, HVAC, municipal engineering, and general fluid handling pipelines.
Our DN100 cast iron wafer butterfly valves are manufactured in strict compliance with international standards, including ISO, ANSI, DIN, BS, and JIS. By combining high-grade cast iron (GG25/HT200) bodies with precision-machined discs and resilient seats, we ensure optimal sealing performance, long service life, and effortless operation for every unit shipped.

Durable Cast Iron Construction: Cast iron provides excellent structural strength, vibration damping, and cost-efficiency for low to medium-pressure applications.
Compact Wafer Design: The space-saving wafer body easily installs between standard flanges, reducing piping stress and simplifying maintenance.
Bubble-Tight Sealing: Equipped with high-resilience EPDM, NBR, or PTFE seats to eliminate leakage and ensure zero-pressure drop across the valve.
Versatile Operation Options: Available with manual lever, worm gear, pneumatic, or electric actuators to match your specific automation and control needs.
