Hedflex Duckbill Check Valve -Flanged (1/2 -96 ) :The JS Valve - HedFlex Duckbill Check Valve -Duckbill Rubber Check Valve, is a cost effective way to control back pressures from sewage treatment plants, outfalls and tidal operations.They are a fully passive flow device requiring neither maintenance, outside sources of power or manual assistance to operate.
Tideflex Duckbill Check Valves have low headloss and achieve the tightest possible seal for backflow operations, particularly at low flow rates. The flexibility of the Tideflex Check Valve allows the valve to compress around trapped solids, providing a much better seal than flapgates. With the development of the patented Curved Bill, sealing ...
