Rubber duckbill valve is a new type of water supply and drainage valve product with a special structure, a "duckbill shaped" appearance, and a "forward discharge, reverse check" function. Made of elastic chloroprene rubber and artificial fibers through special processing, the valve body is made of full rubber structure, and some products may also contain reinforced structures such as nylon curtain layer inside. Its connection methods are divided into sleeve type, embedded type, built-in type, flange type, installation plate type, mortar or cement pipeline type according to the installation method. Common types include clamp type and flange type connections.
Sealing performance: The rubber duckbill valve has excellent sealing performance, which can prevent liquid or odor from flowing back and effectively block the backward propagation of sound downstream of the pipeline.
Pressure resistance performance: Its valve body is particularly flexible, ensuring maximum pressure resistance while minimizing hydraulic loss, achieving a perfect combination of discharge and pressure resistance.
Automatic cleaning function: The special flow channel design inside the valve body ensures that the valve has automatic cleaning function, without sediment and sludge deposition.
Antifreeze performance: The valve body has good flexibility and elastic deformation, therefore it has good antifreeze performance.
