Product Description

No Drip Leak Proof Silicone Duckbill Check Valve for Inverted Squeeze Bottles

When it comes to dispensing thick sauces, finding the right valve can make all the difference. Traditional valves often struggle with thick and viscous liquids, leading to inconsistent dispensing and clogging. Fortunately, silicone duckbill check valves offer a solution to this problem. A duckbill check valve is an essential component for sauces dispensing in inverted squeeze bottles. It is a one-way valve that allows the flow of liquid in one direction and prevents backflow. This valve is particularly useful for sauces dispensing as it ensures that the sauce does not leak or drip out of the bottle when it is not in use.

Product Information

Made of eco-friendly food grade silicone and processed by compression molding, the duckbill check valve consists of a flexible rubber sleeve with a small slit or "duckbill" at one end. When pressure is applied to the valve, the slit opens, allowing the liquid to flow through. When the pressure is released, the slit closes, preventing any backflow.
