Manual Resuscitator Silicone Duckbill Gasket Silicone Duckbill Gasket, also called silicone duckbill valve, slit cutting valve gasket, washer sheet, which is made of elastic silicone rubber materials and made by slit cutting, used as one-way controls or pressure relief valve.
Duckbill Gasket 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 duckbill gaskets 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 duckbill gaskets 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. One way valves are used for controlling the direction of flow of a fluid. Designs can include umbrella valves gasket, duckbill valves gasket, Belleville Valves gasket and diaphragm valves etc.
One way 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. Silicone Duckbill Valve, mostly used in the Patient Valve for Manual Resuscitator.
