Rubber duckbill check valves
Fabric-reinforced rubber duckbill backflow preventers in slip-on, flanged, jacket, in-line flanged and insert styles; CPO and CPF suit marine outfall diffusers.
Description
EVR duckbill check valves need no external power and have no mechanical moving parts to break or jam. A fabric-reinforced rubber duckbill sleeve gives maximum flow with minimum pressure drop, handles raw sewage, sludges and slurries, and seals around trapped solids. Valves install horizontally or vertically.
Key features
- CPO slip-on and CPF flanged: ideally suited to marine outfall diffusers
- CPJ jacket series
- CPI in-line flanged, drilled to all flange standards
- CPI-IN insert type, held inside an existing pipe by an expandable 316 stainless steel internal clamp
Applications
In marine settings, EVR duckbill valves control groundwater and prevent flooding in port areas, allowing safe discharge of heavy rainfall into the water without the risk of backflow. They are also used on outfalls and in sewage and stormwater systems.
