The Orbinox model RC and RR Flap Gate Valves are designed for discharge lines such as levees, sewer lines and drainage conduits. The flap stays closed preventing water back-flow, and it opens automatically when the unseating water head is higher than the seating water head. From sizes 6”x 6” to 56” x 56” the RC square Flap Gate and the RR round Flap Gate have a unique seal design, resulting in a substantially watertight performance. Orbinox can also design and manufacture the RC and RR models in larger sizes. For more information, please contact an Orbinox representative.​

The standard RR and RC models are manufactured in stainless steel which has a higher corrosion resistance in many applications which results in a longer life cycle with little or no maintenance. Other materials of construction are available upon request, such as AISI 904L, Duplex stainless, etc.
