In-line Rubber Duckbill Check Valve – Series CPI-IN 

 Printer-friendly

Designed to be mounted inside a pipe, the CPI-IN Rubber Duckbill Check Valve easily handles corrosive or abrasive materials such as raw sewage, sludge or slurries. Their flexible design allows solids to pass through unhindered and can even surround solids trapped in the valve. Series CPI-IN Rubber Duckbill Check Valves are versatile and can be installed either vertically or horizontally. An expandable 316 stainless steel internal clamp is used to hold the check valve in place once installed.
