Product feature and application

Feature

Our flanged butterfly valve is designed with an integral flange structure, featuring stable and firm connection, excellent bidirectional sealing performance and high pressure resistance to effectively prevent leakage. The valve body is made of high-strength ductile iron, which is corrosion-resistant, wear-resistant and has a long service life. It operates smoothly with low torque and low flow resistance, ensuring stable flow regulation. Meanwhile, it is easy to install and maintain, suitable for long-term stable operation under various harsh working conditions, and meets international standards such as GB/T 12238 and API 609.

Application

Widely used in on-off and flow control of fluid pipelines in various fields, including water supply and drainage systems, sewage treatment plants, fire protection systems, HVAC engineering, chemical industry, municipal engineering, power plants, metallurgy and general industrial fields. It is suitable for various media such as water, sewage, air, oil, weak corrosive fluids, and is an ideal valve product for industrial and civil pipeline systems.

Product details

The flanged butterfly valve exhibits a sleek, industrial-grade finish derived from high-quality ductile iron. Its body is precision-cast from ductile iron (GGG50), renowned for exceptional strength, durability, and resistance to corrosion and wear. The core sealing component features a soft seat (EPDM/NBR/Viton) in a contrasting black or deep gray tone, ensuring a tight, leak-proof seal.

Crafted with advanced foundry technology, the valve body undergoes strict quality control to guarantee uniform density and structural integrity. The precision-machined disc and stem ensure smooth operation with minimal torque, while the flange ends are finish-machined to exacting tolerances for a secure, gasket-free connection. Designed for reliability, it complies with international standards and delivers stable performance across a wide range of pressures and temperatures.
