Product Overview
It is a high-pressure gate valve forged as a whole, with diameters ranging from 1/2 to 24, i.e., DN600. It is mainly used in steam pipelines of thermal power plants with Class 150~4500 working temperature -29~425℃ (carbon steel) or -29~650℃ (stainless steel, chromium molybdenum steel) to shut off or connect the medium in the pipeline. With different materials selected, it can also be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, and urea. It is used for cutting off or connecting media in pipelines of various working conditions such as chemical and thermal power plants. Applicable media: water, oil, steam, etc.
Operation methods include: manual, gear drive, electric, etc.
Application Range
◆ 200MW, 300MW, 600MW, 1000MW thermal power generating units; water supply system, high-add system, main steam system, reheat steam system.
