The Oxygen-specific Globe Valve is a globe valve specially designed and manufactured for oxygen service. Due to oxygen's flammability and strong oxidizing properties, oxygen pipelines have extremely strict requirements for valve selection, including oxygen compatibility of materials, internal cleanliness (must be strictly degreased and free from oil and contaminants), excellent sealing performance, and special structural design to prevent friction and sparks. This valve achieves precise control and tight shut-off of oxygen flow through the linear movement of its disc along the fluid's centerline, ensuring high safety and reliability in oxygen transport and use. It is widely applied in critical areas using oxygen, such such as steel, metallurgy, chemical, medical, and aerospace industries.
