Description

N/A

TheWaterman 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 5º seat on sizes six inches to twenty-four inches and 2 1/2º seat on sizes 30 inches to 60 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.

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.
