Product Overview
The welded metal hard-sealed butterfly valve adopts a precise J-shaped elastic sealing ring and a triple-offset multi-layer metal hard-sealed structure. It is widely used in industrial pipelines such as metallurgy, power, petrochemical, water supply and drainage, and municipal construction with medium temperatures ≤ 425°C, for flow regulation and fluid shut-off. The valve adopts a triple-offset structure; both the valve seat and disc sealing surfaces are made of stainless steel with different hardness levels, providing good corrosion resistance and a long service life. The valve has a bidirectional sealing function, and the product complies with the national standard GB/T 13927-92 for valve pressure testing.

Product Features

1. Adopts a triple-offset structural design, making the valve an ideal hard-sealed butterfly valve for bubble-tight sealing in high-temperature, high-pressure, and fire-safe applications.

2. Due to the welded structure, zero leakage is achieved at the interface between the valve and the pipeline.

3. This valve is flangeless, bringing great convenience and aesthetics to pipeline insulation and wrapping.
