When to choose a Rotary, Spool or Food Valve

Valves play a central role in filling machines in controlling the product flow.  Spool and rotary valves each have distinct features making them suitable for application requirements. We explore these valves’ characteristics, advantages, and typical uses to help you decide which is right for your needs. 

Rotary Valves

Rotary valves utilise a rotating mechanism within a valve body to control product flow. The rotating component has cavities that align with the valve body’s inlet and outlet ports.  As the rotor turns, it either allows the product to flow through or blocks the passage, thus controlling the dispensing process.  The rotation of the valve’s rotor is driven by an actuator, which is the key to open or close the valve.  Packserv’s rotary valves for filling machines can withstand temperatures up to 65 degrees Celsius making it suitable for a wide range of applications at room temperature.

Spool Valves

Spool valves control the direction of fluid flow and are slightly faster than rotary valves. They consist of a cylindrical spool that slides within a housing to open or close different flow paths. Spool valves are ideal for products that are over 65 Degrees Celsius as they are constructed from high-grade stainless steel. In high-temperature applications, the reliability of spool valves ensures safe operation, minimising the risk of leaks or failures.

Food Valves

As the name suggests, food valves are designed specifically for the food industry. They are made of food-grade materials that comply with strict hygiene and safety standards. These valves are designed to be easy to clean and maintain minimising the risk of contamination. They are made from high-quality stainless steel, which is resistant to corrosion and easy to sanitise. Food Valves can withstand temperatures of over 65 Degrees Celsius.

Choosing the Right Valve

When selecting a valve for your application, consider the following factors:

  • Application Requirements: Determine the specific needs of your application, such as the type of material being handled, the temperature, the required flow rate, and the operating environment.
  • Material Compatibility: Ensure the valve material is compatible with the substances it will come into contact with. Rotary Valves are not appropriate for aggressive chemical substances
  • Regulatory Compliance: For food applications, choose valves that comply with relevant safety and hygiene standards.
  • Maintenance and Durability: Consider the ease of maintenance and the expected lifespan of the valve.

Conclusion

Choosing the right valve is essential for optimising the performance and efficiency of your filling production line. Spool valves offer precision and durability for high-temperature applications and aggressive chemicals. Food valves are suitable for both high temperature and room temperature products which are either chunky or smooth. Rotary valves provide efficient filling for a range of products and are rated to handle applications up to 65 Degrees Celsius.

By understanding the unique features and benefits of each type of valve, you can make an informed decision that meets the specific needs of your application. Whether you need precision control, hygienic design, or efficient bulk material handling, there is a valve designed to meet your requirements.
