The eight word blind plate is also called the eight word blind plate, as the name suggests its shape is like the eight word, one end of it is the blind plate, the other end is combined by the throttle ring, in the delivery of fluid, the use of the throttle ring, cut off the use of the blind plate, a bit like the role of the cut off valve, it can be used to cut off when the valve leakage, its sealing performance is better.For systems that require complete isolation, it is generally chosen as a reliable means of isolation.There shall be two globe valves before and after the type 8 blind, and replace the type 8 blind when all are closed.Common heat exchanger service and standby, reactor service and standby, nitrogen pipeline and process pipeline connection, etc.Another feature is the obvious identification, easy to identify its installation status.

The main function of the type blind is to completely block off, just like the function of a gate valve with 100% reliable performance, which will not be misoperated by people.

General Purpose:

1. The system medium pipelines, such as those used for steam purge and those used for process medium pipelines of oil products, play a secure isolation role. In this case, the 8-character blind plate should be installed on the side close to the system medium pipelines.Of course, for the online disassembly of the type 8 blind, there should be gate valve partition on the side of the pipeline close to the process medium. The general sign of such type 8 blind is normally closed.

2. Double gate valves shall be installed in the combustible or toxic medium pipelines of the inlet and outlet devices. See installation of the type 8 blind plate on the double gate valve, which is generally marked as normally open.
