As the opening and closing device on the oxygen pipeline in the metallurgical industry, the Oxygen Butterfly Valve has many particularly strict requirements compared with other general valves. Because oxygen is a flammable and explosive dangerous product, it must be leak-proof, anti-static, and spark-proof to avoid accidents. In terms of structure, the design is: frictionless seal, which effectively reduces the wear of the seal pair, packing wear and upper seal wear; grounding screws are installed on the side flange to avoid static sparks; the exposed part of the valve stem needs to be dust-proof and oil-proof. Oxygen Butterfly Valve has the advantages of good sealing performance, light and flexible operation, safety and reliability, and long service life.

Coal gas butterfly valve is a commonly used in the metallurgical, chemical and other fields in the ventilation pipe, is mainly responsible for containing dust cold, hot air flow, flow regulation and cut off, so it seems gas butterfly valve does not seem any remarkable, However, compared with the normal valve, butterfly valve structure is more suitable for this work environment.

Precautions for oxygen valve operation
◆ The Oxygen Butterfly Valve should be opened and closed slowly. The operator should stand on the side of the valve and open it all at once.
◆ It is strictly prohibited to use oxygen to blow the pipeline or use oxygen to test leaks and pressure.
◆ The operation ticket system shall be implemented, and the operation purpose, method and conditions shall be explained and stipulated in more detail in advance.
◆ Manual Oxygen Butterfly Valves with a diameter greater than 70mm are allowed to operate when the pressure difference between the front and rear of the valve is reduced to within 0.3MPa.
