The difference between blind, spectacle blind and blind valve

Blind Plate Introduction

Blind plate is solid metal plate, used to completely isolate the pipeline, need to be manually disassembled and installed, suitable for one-time or long-term isolation scenarios (e.g., pipeline pressure testing, maintenance).

Spectacle Blind Flange Introduction

Spectacle blind flange plate is in the shape of “8”, one end of the blind plate, the other end of the hollow ring, can be rotated to switch the isolation and conduction state, no need to completely disassemble, saving time, commonly used in frequent switching systems (such as heat exchanger backup piping).

Line Blind Valve Introduction

Blind valve combines valve and blind function, through the drive device (manual, electric or hydraulic) to achieve rapid isolation, easy to operate, suitable for gas media (such as gas, toxic gases) emergency cut off, both sealing and automation features.

The difference between the blind, spectacle blind and blind valves

The core difference between the three is that the blind plate is a static isolation part, the figure-of-eight blind plate can be dynamically switched, and the blind valve has an integrated drive mechanism, which is applicable to scenarios ranging from basic isolation to high-risk gas control in a step-by-step upgrade.
