PRODUCT OVERVIEW
Oxygen special copper ball valve is a kind of valve for oxygen pipeline, which has the characteristics of good flame retardancy, good conductivity, fast heat transfer, compact structure, oil resistance, safety and reliability, etc. It is suitable for media with severe working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, and is widely used in various industries.
PRODUCT FEATURES
1. Fire prevention and fire suppression: The main components are made of copper alloy, which is nonflammable, and will not generate sparks even if they collide with solid particles in high-speed airflow. Therefore, this valve has the BEST fire-proof and fire-proof performance;
2. Safety and reliability: This valve is equipped with dust-proof, water-proof and oil-stain-proof devices. All valve parts in contact with oxygen are strictly degreased and oil-forbidden before assembly. The packing material is polytetrafluoroethylene, which can ensure safety and reliability during use.
3. The flange ends are provided with conductive screw holes to prevent static electricity.
