The attention of our customers and especially of those Interested in.
Water Works, Gas Works or Mines is respectfully called to our very imperenng improvement in the construction of Stop Valves (or Gates). They
iffer from all ethers in that the inner faces are perfectly parallel, therefore when the Gate or Valve is to he opened, at the first movement of the
screw the center hlock (see cut) releases the disks from their bearings, so
that they will move easily and prevent the wearing of the inner faces.
This Gatehas proved very efficient in Pipes of all sizes, and under any
pressure aud from its double form and perfect joint formation is especially
valuahle for nse in large Pipes tor water, steam and gas, and from its
avoidance of any wedge shape cannot jam at any point (see cut).
', e G. «& IS. Valves (or Gates)have no equal in simplicity of construction_of all working parts, ease of access for repairs, and durahility.
