All copper oxygen lift check valve-Oxygen valve series-氧气阀厂家-上海冠环阀门制造有限公司

Product overview

The all-copper oxygen lift check valve is made of silicon brass or stainless steel with excellent material, which has the advantages of high mechanical strength, wear resistance and good safety. Used on the oxygen pipe, with explosion-proof and flame-retardant performance, eliminating the unsafe factors on the oxygen pipe. It is suitable for oxygen pipe network and other systems as a check valve, which plays the role of stopping the flow and stopping the return, such as oxygen rich system to prevent the cold air backflow, and prevent nitrogen and oxygen in the slag splash furnace.

Performance characteristics
1, the valve is generally suitable for clean media, not suitable for media containing solid particles and large viscosity.
2, the valve bushing is made of special materials with good wear resistance and small friction coefficient, flexible and reliable action, and excellent sealing performance.
3. The valve has novel structure, small size, light weight, small fluid resistance, stable opening and closing, long service life, oil pressure and slow closing are not affected by the medium, and has good energy-saving effect.
4, the valve can be installed at the pump outlet, can avoid the production of water hammer, water percussion sound and destructive impact, to prevent countercurrent and protect the purpose of equipment.
