Stacey Valve Company, Brooklyn, N.Y., is offering a catalog that gives detailed specifications and operating features of its 601-AJ Spectacle Line Blind. This blind, particularly suited for shipboard fuel and liquid cargo lines, is said to provide positive dead-tight shutoff in piping from 2 to 18 inches.
With the Stacey 601-AJ blind, opening is accomplished by a single turn of three bolts. The spectacle is rotated to the desired position—with either the "blind" plate or the full-bore "open" plate in the pipeline—and the bolts are retightened. A short steel bar or pipe is the only tool required. The exposed plate of the spectacle indicates the status of the blind at a glance, even from a distance, a valuable safety and maintenance feature.
