The design and manufacture of API carbon steel gate valves must comply with API 600 standards. A216 WCB (alloy carbon steel) or A351 CF8M (stainless steel) is usually used as the valve body material. The pressure rating covers from 150 pounds to 600 pounds (Class 150-600) and can be expanded to higher pressures.
The connection methods of API carbon steel gate valves include flange connection (RF/RTJ), butt welding connection (SW), threaded connection (BSPT/BSPP) and socket welding connection.It is widely used in petrochemical, electric power, oil refining and other fields to cut off or connect fluid media in pipelines.
▪The gate valve body use carbon steel, design standard comply with API 6D API 600
▪Compared with ductile iron valves, carbon steel valves can adapt to a wider temperature range, ranging from –29 to 425°C.
▪Carbon steel gate valve is suitable for saturated steam and superheated steam, high and low temperature oil, liquefied gas, compressed air, water, natural gas, etc.
▪Good corrosion resistance: Carbon steel gate valves can work stably in a variety of chemical media such as acids, alkali, and salts, and are not prone to corrosion and oxidation reactions.
