Lug butterfly valveThe driving mode of the lug butterfly valve can be manual, worm gear, pneumatic, or electric. The connection mode can be flange or clamp. The structural form can be single eccentric, centerline, double eccentric, or triple eccentric. The sealing structure can be soft or hard seal. The pressure range is PN0.1-10Mpa, and the nominal diameter is DN40-2000mm. The material can be cast steel or stainless steel. Due to the wide range of valve applications, the same type of valve can have different combinations in different situations and working conditions.

Gate valveA gate valve is an opening and closing component, and its movement direction is perpendicular to the fluid direction. A gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. Gate valves are sealed by the contact between the valve seat and the gate plate, and the sealing surface is usually welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc. There are rigid gate valves and elastic gate valves. According to the different gate valves, gate valves are divided into rigid gate valves and elastic gate valves.

Detachable butterfly valveWelded butterfly valves use precision J-shaped elastic sealing rings and three eccentric multi-level metal hard sealing structures, and are widely used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction where the medium temperature is ≤ 425 ℃. They are used to regulate flow and load and break fluids. Welded butterfly valves are divided into cast steel welded butterfly valves, stainless steel welded butterfly valves, and chromium molybdenum steel welded butterfly valves. Welded butterfly valves adopt a three eccentric structure, and the valve seat and disc sealing surface are made of different hardness and stainless steel, with good corrosion resistance and long service life. This valve can have two-way sealing function, and the product meets the national GB/T13927-92 valve pressure test standard.
