Preventing backflow through a drainage system is a major consideration when the receiving water is tidal. Stantec Engineering specified Proco Products inline Model 790 valves for their design that included both round and elliptical concrete pipes for a neighborhood drainage project in Manatee County, Fla.

Proco has been making all-rubber check valves for decades. As a standard, all of their drainage check valves are manufactured completely with a top-quality barnacle- and algae-resistant chloroprene rubber. Algae- and barnacle-resistant rubber reduces maintenance intervals and prolongs the valve’s useful life. These valves will never corrode — not even in salt water. They will not stick open or stick closed.

The Model 790 valves are a robust, reinforced unibody design with super low cracking pressure and headloss. The valve is installed fully inside the host pipe; nothing is protruding past the pipe end. This is a great option for boat traffic, easement considerations and for aesthetics. Stainless band expanding clamps anchor these valves from the outfall cuff end or the clamps can be moved to the valve’s inlet side for structure/upstream installations.

Proco offers their inline 790 valves from as small as 2” (50 mm) up to 96” (2,400 mm) round and up to 68”x106” for elliptical sizes. WW
