1. Product Overview

Based on the introduction of advanced foreign technology, Haoshi adopts precision J-shaped elastic sealing rings and three-eccentric multi-layer metal hard sealing structures. It is widely used in metallurgy, electric power, petrochemical industry, and water supply and drainage where the medium temperature is ≤425°C. It is used to regulate flow and load-break fluids on industrial pipelines such as municipal construction and municipal construction. The valve adopts a triple eccentric structure. The valve seat and disc sealing surfaces are made of different hardness and stainless steel. It has good corrosion resistance and long service life. This valve has a two-way sealing function. The product complies with the national GB/T13927-92 valve pressure Test Standard.

2. Characteristics

1. The triple-eccentric butterfly valve can be called a top process valve. This design makes the valve an ideal hard-sealed butterfly valve for bubble-level sealing in high-temperature, high-pressure, and fire-proof applications.

2. Due to the welded structure, the valve and pipe plane achieve permanent zero leakage.

3. This valve has no flange, which brings great convenience and beauty to pipes and insulation bandages.
