Silicone Valves: Fluid Flow Control Dispensing Valves

Duckbill Valves

Duckbill valves are a type of one-way valve that allows fluid or air to flow in only one direction. They are commonly used in various industries, including medical, automotive, and wastewater treatment. The unique design of duckbill valves allows them to provide reliable and efficient performance in a range of applications.

Umbrella Valves

Umbrella valves are a type of check valve that is commonly used in various industries. They are designed to allow fluid or gas to flow in one direction while preventing backflow. The valve consists of a flexible diaphragm that opens and closes as pressure changes, allowing fluid to pass through in one direction and preventing it from flowing back in the opposite direction. Their simple design and low maintenance requirements make them a popular choice for many industries.

Silicone One Way Valves

Silicone one way valves are designed to allow fluid or gas to flow in one direction while preventing backflow. The unique properties of silicone, including its flexibility, durability, and resistance to extreme temperatures and chemicals, make it an ideal material for one-way valves. Silicone one-way valves are an important component in many industries, offering a range of benefits including reliability, versatility, and ease of maintenance. Their unique properties make them an ideal choice for applications where precision and hygiene are critical, and they continue to be a popular choice among engineers and manufacturers worldwide.

Silicone Flapper Valves

Silicone flapper valves are made from high-quality silicone material that is known for its durability and resilience. Silicone flapper valves offer a reliable and cost-effective solution for controlling the flow of liquids and gases in various applications. Their durability, flexibility, and resistance to extreme conditions make them an ideal choice for many industries.

Silicone Non-Return Valves

Silicone non-return valves are an essential component in many industries, including medical, food and beverage, and pharmaceuticals. These valves allow for the flow of fluid in one direction while preventing backflow. Made from high-quality silicone, they are durable, long-lasting, and resistant to extreme temperatures and chemicals. Their durability, resistance to extreme conditions, and easy maintenance make them a popular choice for businesses looking to ensure the safety and efficiency of their operations.

Benefits of Silicone Valves

One of the key benefits of silicone valves is their leak-proof design. When there is no pressure, they work like a silicone gasket and have a perfect sealing effect. However, once there is a certain pressure, the slit will open, allowing for fluid flow control. Silicone valves also offer several advantages over other types of valves.

- Temperature Resistance

Silicone valves can withstand extreme temperatures ranging from -40°C to 200°C. This makes them suitable for applications that require high-temperature resistance, such as medical sterilization, food processing, and chemical manufacturing.

- Bio-compatibility

Silicone valves are biocompatible, meaning they can be used in medical devices and implants without causing any adverse reactions. They are also FDA-approved for use in food contact applications.

- Durability

Silicone valves are highly durable and long-lasting. They can withstand repeated use and exposure to harsh environments without degrading or losing their performance.

Disadvantages of Silicone Valves

Despite their many advantages, silicone valves do have some limitations. Firstly, they are relatively expensive compared to other types of valves due to the high cost of the silicone material and the complex manufacturing process.

Applications of Silicone Valves

Silicone valves have become an essential component in many industries due to their excellent properties, including flexibility, durability, and resistance to high temperatures. These valves have found their way into various applications, including food and beverage production, household cleaning agents manufacturing, personal care products dispensing control, medical devices such as catheters and feeding tubes.

Food & Beverage

In the food and beverage industry, silicone valves are used in the production of dairy products, ketchup, honey, mayonnaise, juices, sauces, and other beverages. They are also used in the packaging of food products to ensure that they remain fresh for longer periods. Silicone valves are preferred in this industry due to their ability to withstand high temperatures and their non-toxic nature.

Household Cleaning

In household cleaning agents manufacturing processes such as detergents and disinfectants production process silicone valves are used . They are also used in the packaging of these products to ensure that they are easy to use and that the contents remain fresh for longer periods.

Personal Care

In personal care products such as shampoos, conditioners, lotions silicone valves are used to control the dispensing of the product. The valves ensure that the right amount of product is dispensed making them cost-effective for manufacturers.

Medical Devices

In medical devices such as catheters and feeding tubes silicone valves are used to control the flow of fluids. The valves are preferred in this industry due to their bio-compatibility which means that they do not harm the body.

Silicone Valves Manufacturing

Silicone valves can be manufactured by compression molding and LSR injection molding, depending on the product structure and quantity demanded. The manufacturing process of silicone valves requires precision and expertise to ensure the quality and reliability of the final product.

Mold Design and Mold Making

The first step in manufacturing silicone valves is mold design and mold making. A professional engineering team with experience in silicone molding and advanced mold making equipment is crucial to ensure high precision and meet the highest standard of the industry. The mold is designed according to the required specifications of the valve, such as size, shape, and material. Once the mold is created, it is ready for silicone molding.

Silicone Molding

After the mold created, the silicone rubber is prepared for molding either to be injected into (LSR Injection Molding) or to be put into (Compression Molding) the mold. During the curing process, the silicone rubber hardens and takes on the shape of the mold. The curing time can vary depending on the size and complexity of the valve, as well as the specific type of silicone being used. Once the curing process is complete, the valve is removed from the mold and inspected for quality.

Slit Cutting

After the valve is removed from the mold, it undergoes slit cutting. Slit cutting is a process where a thin blade is used to cut a slit in the valve. This slit allows the valve to open and close as needed to control the flow of liquids or gases. The slit cutting process requires precision to ensure that the slit is cut at the right angle and depth. YEJIA has developed the automatic punching equipment successfully, not only improve the daily capacity, but also redue the defective rate.

Quality Inspection

The final step in manufacturing silicone valves is quality inspection. The valve is inspected for any defects or imperfections that may affect its performance. Quality inspection ensures that the valve meets the required specifications and standards of the industry. Only after passing quality inspection, the valve is ready for use in various industries.
