In recent years, with the development of China's national economy, high pressure flange connecting steel gate valve industry as an important part of mechanical equipment manufacturing industry, has a very important role.

High-pressure flange connecting steel gate valve is not only widely used in industrial field, but also has a growing influence in the civil field.

Before installation, must carefully check the high-pressure flange connecting steel gate valve standards, the size of the use of the requirements to eliminate the transport process caused by defects, and eliminate high-pressure flange connection steel gate valve dirt, ready to install before the preparation, all ready. When installing, the high-pressure flange is connected to the steel gate valve, which is connected directly to the pipe, and is installed according to the position used. Under normal circumstances, can be installed in any position in the pipeline, but need to facilitate the operation of the overhaul, pay attention to the high pressure flange connecting steel gate valve medium flow should be longitudinal disc below to high, high-pressure flange connection steel gate valve can only be installed horizontally. High-pressure flange connection steel gate valve in the installation should pay attention to sealing, to prevent leakage phenomenon, affecting the normal operation of the pipeline.
