LYV®️ large DN size oxygen ball valve is a special valve specially designed for oxygen pipe network, which is widely used in the pipe network of steel, metallurgy, petrochemical, chemical and other oxygen-using projects. In addition to the functions of ordinary valves, it also has its own characteristics such as good flame retardancy, good electrical conductivity, fast heat transfer, compact structure, oil resistance, safety and reliability. Strict oil prohibition measures are adopted during manufacturing, and all parts are subjected to strict degreasing treatment before installation. All diameter valves are equipped with conductive screw holes at the flange ends to prevent static electricity. The exposed parts of the valve have protective measures to prevent dust and oil pollution. With the valve seat of the metallurgical industry, the special oxygen ball valve and the special oxygen stop valve are widely used in steel, medicine, chemical and other industries.
