Product Introduction

Rubber Duckbill Drain Valve, also known as Duckbill Drain Valve, Silicone Drain Valve, Flanged Duckbill Drain Valve. Rubber Duckbill Drain Valve was named by its shape, under the condition of no internal pressure, the duck beak outlet closed under its own elasticity. As the internal pressure gradually increases, the outlet of the duck's beak gradually increases, and the liquid can be discharged at a high velocity.

Rubber Duckbill Drain Valve Application

Rubber Duckbill Drain Valve is mainly used in waterproof system, drainage system, water pump outlet, lifting pump station and liquid aeration system.The Rubber Duckbill Drain Valve body has an all-rubber design that prevents silting and sticking, reduces maintenance costs, and allows solid particles to pass through smoothly. Flanged Duckbill Drain Valve body manufacturing materials: neoprene, nitrile rubber and ethylene propylene rubber.

Rubber Duckbill Drain Valve Material

1. 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℃.

2. 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 120or in the oil of 150℃. While their cold tolerance and storage stability are not very well.

3. Neoprene Rubber/ CR Drain Valve features good Physical Properties, Oil resistance, heat & flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance and chemical resistance.

4. Fluorosilicone & FVMQ Duckbill Drain Valves have good resistance of oil and strong acid | alkali |oxidant, and also have common silicone advantage like working temperature: -40℃ ~ 230℃
