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,
