Welcome to our dedicated product category for heavy-duty industrial fluid control solutions. As a leading China 10 inch ductile iron manual wafer butterfly valve manufacturer, we engineering and deliver high-performance, cost-effective quarter-turn valves designed for demanding water, HVAC, and general industrial pipelines.
If your projects require dependable flow isolation, compact space savings, and long-term mechanical reliability, our 10 inch ductile iron manual wafer butterfly valve lineup provides the optimal balance of strength, corrosion resistance, and operational ease.
A 10-inch wafer-style butterfly valve is a critical component in medium-to-large piping systems, offering smooth throttle control and reliable zero-leakage shutoff. Our valve architecture is engineered with specific features to maximize operational lifespan:
High-Strength Ductile Iron Body: Constructed from high-tensile GGG40 / QT450 ductile iron, providing superior pressure resistance and impact strength compared to standard cast iron.
Compact Wafer Design: The space-saving wafer body slips easily between companion flanges (ANSI 150, PN10, PN16, JIS 10K), making installation quick and reducing overall pipe support stress.
Smooth Manual Operation: Equipped with a rugged lever handle or an enclosed worm gear operator, allowing smooth, low-torque operation even under full differential pressure.
Resilient Soft Seating: Featuring replaceable EPDM, NBR, or PTFE seats for bi-directional bubble-tight sealing and minimal maintenance down-time.
Due to its versatile material compatibility and durable mechanics, the china 10 inch ductile iron manual wafer butterfly valve is widely deployed across a variety of commercial and municipal sectors, including:
Municipal Water Supply & Wastewater Treatment: Efficient flow regulation in large-bore water filtration and distribution lines.
HVAC & Industrial Cooling Systems: Reliable isolation for chilled water, condenser water, and tower circulation.
Fire Protection & Irrigation Networks: Dependable shut-off capabilities for high-volume agricultural and fire safety systems.
Procuring large-diameter manual valves directly from an established factory ensures complete control over technical specifications, product testing, and project budgets. By eliminating intermediary trading companies, we deliver direct factory pricing and end-to-end quality assurance on every order.
Every 10-inch valve undergoes strict shell and seat pressure testing according to API 598 or EN 12266-1 prior to packaging. We support customized OEM requests, including epoxy powder coating colors, customized stem dimensions, brand tagging, and complete material test certificates (MTRs).
