Oxygen Butterfly Valve

Oxygen valve as a metallurgical industry to transport oxygen pipeline opening and closing devices, compared with other general valves have many special strict requirements. Because oxygen is a flammable and explosive hazardous material, it is necessary to prevent leakage, anti-static, and spark-proof to avoid accidents. In the structure, the design is as follows: when the valve flap opens and closes, the valve stem only lifts and does not rotate, which effectively reduces the wear of sealing vice, packing wear and wear of the upper seal; the side flanges are equipped with grounding screws to avoid static sparks; the exposed part of the valve stem is sealed with Plexiglas, which is used to prevent dust and oil.
