The blind plate is mainly used to completely isolate the production medium to prevent the shut-off valve from being tightly closed, affecting production and even causing accidents. Blind plates should be installed in the parts that require isolation, such as the equipment connection port, the front and back of the shut-off valve, or between two flanges. It is often recommended to use 8-shaped blind plates; plugs can also be used for single-use parts such as pressing and purging. Plate (round blind plate).
