Rubber Duckbill Drain Valve
Duckbill drain valve is also called as flange type duckbill valve, rubber sewage check valve, and rubber drain duckbill check valve.
Rubber Duckbill drain valves are mainly used in waterproof systems, exhaust systems, water pump outlets, lifting pump stations and submerged aeration systems
Silicone Duckbill Drain Valves’ Main features:
drain valve is integrated with the valve body, and is extremely convenient to install. The valve have good design (completely one way valve) so that will not cause siltation and jamming, and can reduce maintenance costs, and also allows solid particles to pass smoothly.
Duckbill Drain Check Valve’ materials:
Neoprene, EPDM, Nitrile rubber and Ethylene-propylene rubber.
EPDM Duckbill Drain Valve have good characteristics of resistance to heat, aging, weather resistance, excellent electrical insulation properties, good chemical resistance and impact elasticity, EPDM is a saturated polymer basically and can be in long-term operation under 150℃.
Buna N & Nitrile Rubber Duckbill Drain Valve is resistant to oil (especially alkane oil) and has good aging resistance. NBR has excellent oil resistance, can be used for long time in the air of 120 ℃ or in the oil of 150℃.
Neoprene Rubber Drain Valve features good Physical Properties, Oil resistance, heat & flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance and chemical resistance.
Fluorosilicone & FVMQ Duckbill Drain Valves have good resistance of oil and strong acid | alkali |oxidant, and also have common silicone advantage like working temperature: -40oC ~ 230oC
Silicone rubber duckbill drain valve’s advantages and applications:
1.Duckbill valve for sewage system
Drain duckbill valve prevents flooding and sewage backflow into the sewers and basements.
2. Duckbill Drain Valve for emission systems
The flanged duckbill valve can prevent the flooding from rising into the urban surface when the water level rises, and the sewage treatment plant drains the pumping station.
3. Rubber Duckbill Drain valve for dam discharge
When the rocky beach is discharged, the problem that plagues the door is that the blockage of the stone garbage makes the door not closed or can not be opened. Using duckbill valve in these areas will completely solve this problem.
4. Rubber Sewage Check Valve for airports, highway drainage
The duckbill valve is used in the airport, and the highway is drained in a large area to prevent backflow.
5. Rubber Drain Duckbill Check Valve for sewage pool discharge
The flanged duckbill valve duckbill valve prevents sewage from flowing from one section of the pre-buried tank to another. And duckbill drain valve will not affected by plastics, branches or silk.
