Revolving discs
vs. solid wedge gate
in marine service
American-Darling Revolving
Discs features:
1. No pockets on discs to collect deposits.
2. Discs contact seats during travel to
remove deposits.
3. Discs revolve with a self-cleaning action
to prevent fouling on body guides.
4. Wedging action is independent of
seating action for easier operation.
5. Internal parts are interchangeable and
reversible for easy maintenance.
Consider these possible
disadvantages of the
solid wedge gate design:
1. Wedge guides in body are subject to
fouling and wear due to line content
deposits.
2. Buildup on seat surfaces are trapped
at seating position causing leakage.
3. Since wedging and seating occur
simultaneously, approximately 50% more
operating force is required than for
Revolving Discs design.
4. Wedge is not usually interchangeable
from valve to valve. Reseating requires
fitting of wedge to body seats.
On your next installation, get all the advantages. Specify American-Darling
Revolving Discs gate valves. For more information, write for our bulletin.
