Product Description:
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.
Features:
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.
