Import Cast Iron Butterfly Valve — Buy in Bulk from Supplier in China

The Tonglu Wanhe Valves Co., Ltd cast iron butterfly valve is a wafer-style flow control device engineered for industrial pipelines, compatible with BS, ANSI, DIN, UNI and JIS standards. It features a cast iron body with a resilient seat design, suitable for water, oils and gas applications in systems up to the pressure ratings typical for this class of valve. The lightweight construction reduces structural load requirements while maintaining durability in demanding environments.

This valve uses a disc-and-seat mechanism for tight shutoff, with sealing properties that minimize leakage and optimize flow rates in both low and high-pressure scenarios. Cast iron is the standard material for such valves due to its cost-effective strength and corrosion resistance in non-acidic media, while the wafer design allows installation between flanges without additional bolting. The valve is commonly specified in sizes from DN50 to DN1200, typical for municipal and industrial water treatment, HVAC and chemical processing systems.

Industrial buyers source this model for pipeline isolation and flow regulation in treatment plants, commercial buildings and process industries. The supplier offers flexible trade terms, including FOB and CIF shipping options, with packaging designed to prevent damage during transit. Buyers should confirm compatibility with their pipeline material and pressure class, as well as any project-specific certification requirements such as ISO or CE marking.

Tonglu Wanhe Valves Co., Ltd is based in Hangzhou, Zhejiang Province, with its production facility located at 139# Xianghe Road in the Fangbu Industry Park. The company operates as an imported-tier supplier, indicating it sources or manufactures components for industrial valve applications, including butterfly, gate and check valves for fluid control systems.

The supplier’s profile shows a harbor trust tier, but currently lists a 0% response rate and no recorded average response time, which suggests buyers should verify availability and communication channels directly. The company specializes in valves for water, chemical and HVAC industries, with a focus on meeting international standards for compatibility and performance.
