Rubber Duckbill Check Valve is a fluid control device commonly used in industrial pipelines to control the flow rate, pressure, and direction of fluids. This valve has a compact design and high reliability, suitable for controlling high-pressure, high-temperature, and corrosive media.
Rubber Duckbill Check Valve flange connection has a long service life, good valve sealing performance, and also features fire resistance, earthquake resistance, corrosion resistance, and high pressure resistance. Widely used in industries such as urban water supply, drainage, and sewage treatment. In these industries, duckbill valves are commonly used to prevent water hammer impact caused by reverse water flow and protect the safe operation of pipelines and equipment.
Rubber duckbill check valve commonly known as: rubber sewage check valve, also known as: back
pressure flexible check valve, duckbill valve check valve, rubber check valve, rubber check valve, rubber slow-closing check valve, etc.
Features of Rubber Duckbill Check Valve :
1. Automatic opening and closing of press differential, safe and reliable, no noise, no manual operation and maintenance.
2. Small positive rotation resistance, small starting pressure, flow according to the water pressure natural regulation.
3. Backcheck valve seal, no leakage, prevent backflow, the greater the backpressure, the better the effect.
4. Corrosion resistance, aging resistance, deformation adaptability, long service life.
5. Size range nominal diameter DN50-DN3000.
