Small Duckbill Valve, also known as Cross Slit Valve, Mini Duckbill Valve.
Duck Bill Valves are one way check valves that open and close at low pressure. Small Duck Bill valves are often placed at the end of an orifice. As pressure is applied, the end that looks like a Duck Bill opens, allowing for the media to pass through. When the pressure is reduced, or stopped, The Duck Bill portion closes, thereby stopping the flow.
Small Duckbill Valve (cross slit valve), not only take full advantage of elastomeric silicone properties, and also make full use of die cutting appliance. Slit cutting valve, which need punching by die tooling after silicone rubber compression molding or LSR injection production. This process is key to duckbill check valves quality.
1. Depends on the diecutting tool: It needs to be sharp enough, so that it can cut the silicone thoroughly
to invoid diecutting burrs, and to invoid the situation of "slit" doesn't close well.
2. Depends on the permanent compression set value: for this kinds of cross slit valve,
need to use high-elastic silicone, so that its restoring forces will be good.
3. Depends on the hardness: generally, cross slit valve with high durometer & hardness
will have better restoring forces.
Small Duckbill Valve has the following special features as small check valves:
1. Small Duckbill Valve & cross slit valve can be assembled in the smallest space.
2. Even in low-pressure situation, cross slit valves & umbrella valves also have keen response performance.
3. The one way check valve has excellent corrosion resistance & frictional resistance performance.
Small Duckbill Valve are mainly used in air control device like medical resuscitators, diving equipments etc.
Cross slit valves are also used in liquid & water controller device like diaphragm pump, toilet products, automotive fuel tanks, outlet valves etc.
