8 Type Blind Flange as the name implies is its shape like the number 8, it is one end of the blind plate, the other end is composed of throttling ring, in the transmission of fluid with throttling ring, cut off the use of 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. It is generally used as a reliable means of isolation for systems that require complete isolation.
