Different types of Design and Disc Material Selections
Engineers select materials for low lift safety valves by analyzing the fluid's properties, operating temperature and pressure, and required mechanical strength, while also considering corrosion resistance and cost. Materials like bronze are common for general steam/air/water applications at lower pressures, while stainless steel is used for corrosive fluids or clean steam, and special alloys are employed for high-temperature or hazardous gas services.
