the flow direction and instantaneous check once flow is stopped
and reverse flow is sensed. Duckbill Check Valves will react,
and hold in check, pressure as low as 0.5 PSI.
This design
utilizes a smaller valve body for use where minimal space
is required. Duckbill CV’s are available in 1/8”
and 3/16” barb size, and can be purchased as Standard
(same size), Reducing, or Enlarging. Duckbill Check Valves
share our standard Check Valve barb design, a barb molded
without a parting line. A very sharp seal point on the barb
seals securely with flexible tubing and has been tested to
hold pressure up to 150 PSI without the use of a hose clamp.
Duckbill Check Valves feature a silicone valve with body material
options of Nylon, Polypropylene, Kynar®, and Polycarbonate.
