Product Description

Oxygen special ball valve QY41F Product Overview:
Silicon brass oxygen pipeline special ball valve belongs to the oxygen pipeline special valve, in addition to the characteristics of ordinary valves, but also in view of its use of excellent quality copper material manufacturing, but also has the advantages of corrosion resistance, good flame retardant performance, good electrical conductivity, fast heat transfer, and so on, coupled with my company's structure on the continuous update and fine process guarantee, Making this series of products has become the ideal equipment in the oxygen control engineering system. As the opening and closing device of oxygen conveying pipe in metallurgical industry, the oxygen ball valve has many particularly strict requirements compared with other general valves. Because oxygen is flammable and explosive dangerous goods, it is necessary to prevent leakage, anti-static, fireproof flower to avoid accidents. In the structure, the design is: the valve stem only lifts and does not rotate when the disc is opened and closed, which effectively reduces the wear of the sealing pair, the wear of the packing and the wear of the upper seal; The side flange is equipped with a ground screw to avoid electrostatic sparks; The exposed part of the valve stem is sealed with plexiglass to prevent dust and oil.
