Spreading Rotating Line Blind (700 Series)

This is the original design for a quick action Line Blind. Depending on the size, 3 to 7 Jack Bolts are being turned to spread the unit, and therefore spread the process pipe. This creates the space to rotate the spectacle plate. By turning the Jack Bolts to the closed position, the unit will seal again.
