Rubber Duckbill Check Valve
Rubber duckbill check valves are unique, one-piece, elastomeric components that act as backflow prevention devices
or one-way valves or check valves. They have elastomeric lips in the shape of a duckbill which prevent
backflow and allow forward flow.
The main advantage of rubber duckbill check valves over other types of one-way valves is that duckbill valves are self
contained i.e. the critical sealing function is an integral part of the one piece elastomeric component as
opposed to valves where a sealing element has to engage with a smooth seat surface to form a seal.
Therefore rubber duckbill
check valves are easily incorporated and assembled into a wide variety of devices without the
hassle or problems associated with the surface finish quality of mating seats and/or complex assembly
Other not less important features include:
2)Low opening pressure- immediate free flow,
3)Non-tortuous flow path,
4)High flow rate vs. package size,
5)Virtually no internal volume and dead space,
8)Wear resistant and
9)very cost effective.
rubber duckbill check valves are used for controlling the direction of flow of a fluid. Designs can include umbrella valves, duckbill valves, Belleville Valves and diaphragm valves etc.
rubber duckbill check valves can be designed to provide the customer's required head loss and flow rate for particular applications.
A range of materials and designs are available to handle different fluids and service conditions.
