Welcome to our specialized manufacturing facility! As a premier China 6 inch ductile iron manual wafer butterfly valve factory, we are dedicated to designing, engineering, and producing top-tier fluid control solutions for modern industrial systems. Our 6-inch ductile iron manual wafer butterfly valves are built to withstand rigorous operating environments, offering exceptional durability, reliable sealing, and long-term cost efficiency for global distributors, wholesalers, and project engineers.
Constructed from high-tensile ductile iron (QT450-10 / ASTM A536), our valves provide significantly higher yield strength and impact resistance compared to standard cast iron alternatives. The compact wafer-type design allows for easy installation between ANSI, DIN, or JIS flanges, saving valuable space and reducing pipeline installation costs.
Equipped with a robust manual hand lever or worm gear operator, this 6 inch ductile iron manual wafer butterfly valve ensures precise flow control and effortless operation. We utilize high-performance seat materials—including EPDM, NBR, and PTFE—to accommodate a wide variety of media, such as clean water, sewage, air, light oil, and non-corrosive industrial liquids.
Durable Body Construction: High-strength ductile iron body ensures resistance to pipeline stress and mechanical impacts.
Tight Bi-Directional Sealing: Advanced vulcanized or renewable seat designs guarantee zero-leakage performance under rated working pressure (PN10/PN16/150LB).
Compact & Lightweight Wafer Design: Fits effortlessly between international flange standards, minimizing overall weight and handling effort.
Corrosion Resistance: Coated with eco-friendly fusion-bonded epoxy (FBE) internally and externally to prevent rust and extend service life.
Ergonomic Manual Operation: Smooth hand-lever or gear-driven mechanisms equipped with locking devices for accurate positioning and safety.
As an experienced china 6 inch ductile iron manual wafer butterfly valve factory, we strictly adhere to international quality management systems, including ISO9001, CE, and API certifications. Every single valve undergoes 100% hydrostatic and shell testing before leaving our production line to ensure flawless field performance.
We offer comprehensive OEM/ODM customization services—from custom painting, custom logo branding, and specialized seat materials to tailored flange dimensions. Whether you are stocking up for distribution or sourcing for large-scale municipal, HVAC, chemical, or water treatment projects, our integrated supply chain delivers competitive factory-direct pricing and fast lead times.
