  • Detail
  • The 8-shaped blind plate is a pipe fitting with an appearance resembling the number "8". It consists of a solid plate (which blocks the pipe) and a hollow ring (which allows the medium to flow). The main function is to switch the "open/closed" state of the pipe, similar to a "switchable valve" in a piping system.
    Core advantages
    Flexible switching, no need for disassembly: To make the pipe open, align the hollow ring; to cut off the flow, align the solid plate. There is no need to repeatedly disassemble the components, saving time.​
    Sealing tight, no leakage: The solid plate is closely attached to the pipe, firmly blocking liquids and gases, preventing leakage or hazards (such as gas or chemical media).​
    Durable and robust: Made of common carbon steel or stainless steel, it is not afraid of high pressure and high temperature, and can last for a long time in industrial environments without easily breaking.​
    Easy to identify safely: The "8-shaped" appearance is prominent, and workers can easily distinguish whether it is "open" or "closed" at a glance, reducing operational errors.​
    Key specifications​
    Material: Carbon steel (high cost-effectiveness), stainless steel (corrosion-resistant, suitable for chemical / food scenarios)​
    Core features: Integrated "8-shaped structure" (solid + hollow combined)​
    Applicable pressure: Medium and high pressure (commonly used in industrial piping, capable of withstanding high pressure)​
    Sealing method: Flange bolt fixation (aligned with the pipe flange, tighten to seal)
