Rubber Duckbill Check Valve

Shuangfu Rubber Duckbill Check Valve is a very reliable and cost effective check valve compare to flap check valves and other conventional check valves.

Rubber Check Valves require minimal maintenance;the simple one—piece design and reinforced rubber construction eliminate the mechanical and metal components that rust and seize in conventional flap—gates and check valves.

Duckbill Check Valve is a passive—reactive device requiring no external mechanisms or power source to operate.The flexible rubber sleeve is normally closed but will react and open with as little as I inch of head pressure and always providing maximum flow with minimal pressure drop across the valve.This ease of operation reduces standing water in sewer pipes where mosquitoes and other pests can thrive.

All the flexible construction will pass large objects without blockage yet offers exceptional back flow prevention and can even seal around trapped solids with as little as I psi of back pressure.

Shuangfu Rubber Duckbill Check Valve is manufactured with top quality materials including an outer layer specially formulated to repel growth of marine organisms.

Typical Applications

• Storm water outfall

• Flood control systems

• pumping stationslVVet wells

• Sewer interceptor check valve

• CSO/SSO/Effluent discharge

• Submerged outfall diffuser nozzles

• Coarse bubble air diffusers

Available Elastomers

Standard construction is a natural gum rubber inner tube with a multi—resistant Neoprene outer cover.Neoprene is also commonly used for the inner tube in sewage and treated effluent applications.Other elastomers are available but not often required where this style of valve would be used.
