Unlike other check valves, Rhinoflex duckbill rubber check valves, available from Rhinoflex Pinch Valves , require less maintenance and they lack interior metal components that can rust or become corroded, and seize. In the Rhinoflex duckbill rubber check valves, there are no seats or seals, flappers, springs and metal bodies. These are engineered from one single piece of specialised rubber, depending upon the application Rhinoflex duckbill check valves are a reliable and cost effective alternative to flap-gate valves and other conventional check valves.
Rhinoflex duckbill check valves are a passive and 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 1-inch of head pressure ensuring 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.
The flexible construction of the Rhinoflex Duckbill check valves will pass large objects without blockage. Yet, the valves offer exceptional back flow prevention and will even seal around trapped solids. The duckbill-shaped design also offers superior performance in pollutant entrapment, high durability, minimum leakage, and various self-cleaning capabilities, which no other valve can offer.
Rhinoflex duckbill check valves can be used in a variety of wastewater, storm water, and backflow prevention applications.
The Rhinoflex duckbill check valves can be used in the following applications:
- Storm water outfall
- Flood control systems
- Pumping stations/wet wells
- Sewer interceptor check valve
- CSO/SSO/effluent discharge
- Submerged effluent diffuser nozzles
- Coarse bubble air diffusers
- Sparging Nozzles
Following are the features of Rhinoflex duckbill check valves:
- Quiet operation
- Minimal maintenance
- Seals around trapped objects
- Low head loss
- Reliable performance
