​​​THE VALVE AGENCY, INC.

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.
