Duckbill Check Valve Working Temperature

Rubber duckbill check valve also called duckbill valve, one way valve is very common used in many industry for backflow prevention.

The rubber flange and the valve body are integrated into a whole, and the installation is extremely convenient. Rubber slow closed check valve body with a full rubber design, will not cause deposition and things stuck phenomenon occurs, reduce the maintenance costs, and allow the smooth flow of solid particles.

Body material: neoprene,  nitrile rubber and EPDM rubber; flange material: Q235304316.

Duckbill valve according to the working temperature can be divided into the following categories:

(1): ultra-low temperature valve for medium temperature valve T<100 C.

(2): used for medium temperature valve operating temperature of 100 DEG C = t = 29 C valve.

(3) at room temperature for medium temperature valve: the valve 29 <t<120 DEG C.

(4) the temperature valve for medium temperature 120 = t = 425 DEG C valve

(5) high temperature valve: valve used for medium working temperature t>450.
