Rhinoflex Duckbill Check Valves
The Rhinoflex Duckbill Check Valves is a one piece, one way, non-return check valve, manufactured fully with a rubber/polyester construction. There are no mechanical parts, seats or seals, springs or flaps and hinges that will break, warp, corrode or freeze and prevent consistent valve operation. This construction makes the Rhinoflex Duckbill Check valves virtually maintenance free, and guarantees reliable, repeatable, trouble-free service for many years. All standard domestic and international drilling patterns, as well as custom made sizes and flanges are available.
The Rhinoflex Duckbill Check Valves comes with 304 or 316 stainless steel backing rings or clamps, for mounting on headwalls tanks and on mating pipe flanges, and to slip on outside the diameter of the pipe. No additional energy source is required, as these valves use the line pressure to open and their design and construction along with back pressure to close. These are normally closed but will open with minimum line/head pressure, always providing maximum flow with minimum pressure drop across the valve.
The Rhinoflex Duckbill Check Valves will close and seal completely around solids, making it ideal for mining slurries, fly ash, raw sewage, sludge, lime, along with suspended solids in waste water and storm water, vapors, air and gas.
