Overview:
This type of multi-point quick-switching blind/goggle valve is suitable for blind plate plugging and extraction operations of large-diameter high-pressure pipelines. Only one worker is required to operate the electric actuator to loosen the left and right valve bodies and move the plate left and right into place. The blind plate plugging and extraction operation of the large-diameter pipeline can be completed in 3-9 minutes.
Features:
Blind/Goggle plate valves have the advantages of novel structure, wear resistance, reliable sealing, flexible operation, convenient installation, maintenance, and long service life. They are equipped with pipeline expansion devices, which can switch valve plates without affecting pipeline facilities. Especially suitable for situations that require quick cutting and reversing.
