Applications for globe valves: Part 3

5. High temperature and high pressure power station globe valve: the structural feature of the valve body and the valve cover is that the connection between the valve body and the valve cover adopts pressure self-tightening sealing type or clamping type, the connection form between the valve body and the pipeline is butt welding connection, the valve body material is mostly made of chromium-molybdenum steel or chromium-molybdenum vanadium steel, and the sealing surface is mostly overcast cemented carbide. Therefore, this type of valve has high temperature and high pressure resistance and good heat resistance; The sealing surface is wear-resistant, scratch-resistant, corrosion-resistant, has good sealing performance and long life. It is most suitable for high-temperature and high-pressure water, steam, oil and superheated steam pipelines in thermal power industrial systems, petrochemical systems and metallurgical industries.

6. API globe valve: This type of globe valve is designed in strict accordance with API 623 -2015 and ASME B16.34; the connection between the valve body and the bonnet, the stuffing box, the installation of the stem nut, the upper seal, etc. are all designed in strict accordance with API 623. The valves are selected in full compliance with API 623 requirements. The length of the structure complies with ASME B16.10 and the flange connection size conforms to ASME B16.5. The valves are inspected and tested in strict accordance with API 598. Therefore, the valve is widely used in petrochemical pipelines, and is also suitable in electric power, metallurgy, textile and other systems.
