Rubber Duckbill Valve and Duckbill Check Valve:
Rubber Duckbill Check Valve and Duckbill Valve:
Rubber check valve also known as: rubber sewage check valve, sewage rubber check valve, rubber check valve, rubber duckbill check valve.
1) quality garantee
2) specific certificate
3) good quality and competetive price
Rubber duckbill check valve size standards:
Mounting dimensions flange connection to the GB, which is the earliest design rubber duckbill check valve by Lee Tongwen engineers, in order to want to match with the national standards, the provisions of the 800 caliber rubber duckbill check valve flange standard mixed GB ten kilograms bolt hole center distance and flange outside diameter, the diameter more than 800 (inclusive), with reference to GB 6 kg bolt hole center distance and flange outer diameter.
Rubber Duckbill check Valve Directions:
1) Open pressure: 0.003MPa, equivalent to a basin of water.
Under normal circumstances, the duckbill check valve can normally 3 meters in the underwater work, but this height is, counting from the bottom of the duckbill check valve, plus special apparatus, can reach 10 meters underwater.
2) Service Life: the design life of two years, but in general, at room temperature, and the climate is bad, you can use five years, even as long as 10 years, but the proposed one-for five years to prevent aging.
3) The head loss of about 5% to 8%.
Rubber duckbill check valve detailed data:
Matdhing Pipeline DN
Rubber Duckbill Check Valve Advantage:
1) Based on the difference in water pressure automatically turn on and off, safe and reliable, no noise, no need for personnel to operate, no maintenance.
2) Forward open water resistance, starting pressure (0.003Mpa), and automatically adjust the flow according to the water pressure.
3) Reverse backstop seal, no leakage, prevent backflow, the greater the back pressure, the better the effect.
4) Anti-corrosion, adaptability, and long service life.
5) A wide range of sizes and nominal diameter DN50-DN2400.
