PRODUCT OVERVIEW
The special all copper stop valve for oxygen is mainly used to connect or cut off the medium in the pipeline. Generally, it is not used to adjust the flow, but it is applicable to a wide range of pressure. Oxygen special valve is a special valve specially designed for oxygen pipe network. It is widely used in the pipe network of oxygen engineering such as iron and steel, metallurgy, petrochemical and chemical industry. The valve not only has the function of ordinary valve, but also has the advantages of high mechanical strength, wear resistance and good safety. Strict oil prohibition measures shall be adopted during manufacturing, and all parts shall be strictly degreased before installation. All valve flange ends are provided with conductive screw holes to prevent static electricity. Protective measures shall be taken for the exposed parts of the valve to prevent dust and oil pollution. When used on oxygen pipeline, it has explosion-proof and flame-retardant performance and eliminates unsafe factors on oxygen pipeline.
PRODUCT FEATURES
1. Fire prevention: the main components are made of copper alloy, which is a non combustible material. Even if they collide with solid particles in high-speed air flow, they will not produce sparks. Therefore, the valve has fire resistance performance.
2. Safe and reliable: the valve is equipped with dust-proof, waterproof and oil proof devices. All valve parts in contact with oxygen are strictly degreased and oil prohibited before assembly. The packing material is PTFE, which can ensure safety and reliability during use.
