The Waterman Red Top Drainage Gate has been designed
as a competitive flap gate for use with concrete pipe, headwalls, and
corrugated metal pipe with up to a ten foot seating head. The frame and
cover are of heavy duty cast iron. Steel angle links have been used to
absorb unbalanced side shock, and are balance-pivoted on bronze bushings.
A 5°seat on sizes six inches to twenty-four inches and 2 1/2°
seat on sizes 30 inches to 72 inches eliminates the need for special pipe
cuts or sections, and prevents the gate from standing open due to slight
pipe sagging or settling. An innovation in the cover provides each gate
with a safety to prevent jamming, without additional cost. Gates are available
with special stainless steel or brass links and bolts as well as bronze
seating faces. This gate has been extensively used on federal, state and
municipal projects for drainage, waste line, sewage treatment, flood control
and irrigation systems. A free outflow with practical sealing against
back flow combine with maintenance-free operation to assure years of service.
This gate is not recommended for pump discharge or other applications
where violent slamming may occur. Heavy-duty links and bushings are available
when severe operating conditions are anticipated.
OPTIONAL ITEMS INCLUDE:
• Bronze seats • Stainless Steel or bronze links, and bolts.
• Special heavy-duty links and bushings for severe service •
Special paint coatings or ASTM galvanizing • Taper setting collars
and special pipe adapters.
