Reverse Slip-In Duckbill Check Valve
Prevents Backflow Inside the Pipe Line
The series DBRS slip-in check valve, like the series DBCP, offers a cost effective method of backflow prevention. It is designed for installation inside of a non-flanged pipe secured by expanding band clamp. The series DBRS slip-in check valve eliminates the mechanical parts which can wear and jam in conventional check valves.
