Duckbill Check Valve Types & Installation and Duckbill Check Valve Design Guide——Duckbill check valve is also named rubber check valve, rubber duckbill valve, which has special structure like duckbill. It is an air, gas, liquid, water backflow preventer which has the function of forwarding flow in positive direction while non-return in opposite direction. Rubber duckbill check valve is applicable widely to drainage system, sewer, breast pump and manual respirator.

Medical Silicone Rubber Valve also knowns as Silicone Check Valve, Silicone One Way Valve, Rubber Non Return valve and Medical Diaphragm Flow Control Valve. Silicone rubber valves used in medical devices are generally duckbill, umbrella, disk, v-ball, combination and bi-directional valves. There are many considering factors, such as material and processing way, when deciding which medical valve is suitable for application.

Resuscitator's duckbill valve also known as ventilator check valve, respiratory & respirator valve, one way breathing valve, which are usually used as medical non return check valve in non rebreathing patient valve, expiratory valve for respiratory device like manual resuscitator & respirator, CPR bag, self inflating bag, bag valve mask(BVM), manual resuscitation & ventilation bag like Ambu Bag, Laerdal resuscitator.

BVM valve also can be called as resuscitator valve and Ambu Bag valve, which function as non return valve in self inflating manual resuscitator to control oxygen flowing for a breathing or non-breathing patient in an emergency situation. Ambu bag valve includes pop-off valve, pressure limiting valve, non-rebreathing patient valve, PEEP valve, and intake valve, consisting of plastic parts and rubber medical check valve like duckbill valve, umbrella valve​, diaphgram disc valve, expiratory valve.

How Does Duckbill Valve Work?Duckbill Valve is one-piece elastomeric component with flexible flaps& lips. By combination of elastomer rubber flexibility & softness and slit cutting function, Duckbill Valve provides the reliable tightest seal for backflow & leakage prevention at low-pressure fluid &

Duckbill umbrella valve & duckill fapper valve are combination valve which function as two way flow control valve, bidirectional valve. Duck bill umbrella valve refer to the valve with a duckbill valve in one side and a mushroom valve in another side while duckbill flapper valve is combined by a duckill walve and a flapper check valve. They are made of FDA / LFGB approved silicone material, widely used for sealing, flow controlling, liquid dispensing & air releasing.

Duckbill Valve Duckbill Valve, also known as One Way Valve, Non-Return Valve, Duckbill Check Valve. Duckbill 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 pre
