What is silicone valve?

Silicone valves are elastomeric valves that are manufactured using silicone materials. These valves are specifically designed to regulate the flow of fluids at predetermined pressures. The manufacturing process involves either compression molding or liquid injection molding. Silicone valves have the capability to dispense liquids, powders, and gases. They serve a dual purpose as both a sealing gasket and a dispensing valve. Under normal conditions with no pressure, these valves provide a secure seal. However, when a certain pressure is applied, the valve opens, allowing the fluid or air to pass through.


Types of Silicone Valves

There are different types of silicone valves available. If classified by materials, the common ones are food grade silicone valves and medical grade silicone valves. In terms of shape, there are various options such as cross slit valves, duckbill valves, umbrella valves, dome valves, flapper valves, vent and relief valves, and more.

Applications of Silicone Valves


The applications of silicone valves span across a wide range of industries. The versatility of silicone valves lies in their ability to provide a perfect sealing effect and effectively control fluid flow.


Cross slit valve is a type of valve that has various applications in the field of food and beverage packaging. This valve is designed to regulate the flow of fluids, gases, and other materials in a system, initially used for dispensing liquids in squeeze bottles like ketchup, mayonnaise, syrup, concentrates and other thin or thick sauces.


Medical check valves play a crucial role in ensuring the safety and effectiveness of various medical devices. Their application is essential in preventing backflow of fluids and gases, which can lead to serious health complications.


Duckbill valve is a type of valve that is commonly used in various applications. It is a one-way valve that allows fluid or gas to flow through it in one direction only. The valve is named after its shape, which resembles the bill of a duck. One of the most common applications of the duckbill valve is in medical devices, such as respiratory equipment and blood pressure cuffs. Its unique design and functionality make it an essential component in many devices and systems.


Umbrella valve is designed to control the flow of fluids or gases in a one-way direction. It consists of a flexible rubber or silicone diaphragm that opens and closes with the pressure difference across it. Umbrella valves have various applications in different industries, including medical devices, automotive systems, household appliances, and industrial equipment. They play a crucial role in controlling the flow of fluids or gases in a one-way direction, ensuring efficiency, safety, and reliability.
