Solenoid Valve Selection Guide for Food Packaging Machinery: How to Choose a Solenoid Valve that Meets Hygiene Standards and High-Frequency Demands

Solenoid Valve Selection Guide for Food Packaging Machinery: How to Choose a Solenoid Valve that Meets Hygiene Standards and High-Frequency Demands

In the food packaging industry, machinery faces two severe tests: it must meet the high-speed, high-efficiency demands of production while strictly adhering to hygiene and safety standards. As the core actuation component of the pneumatic system, the solenoid valve's selection not only affects the machine's performance but also directly influences the quality and safety of the final product.

To ensure equipment operates continuously and stably in high-speed, high-frequency, and frequently washed-down environments, the selection of the right solenoid valve is crucial. This article will provide a detailed look at how to choose the most suitable AirTAC solenoid valve products based on the unique demands of food packaging machinery.

 

The Unique Demands of Food Packaging Machinery

 

Food packaging machinery has requirements for solenoid valves that far exceed those of general-purpose equipment:

  • Hygiene and Cleanliness: Valves must be made of materials that are easy to clean to prevent bacterial growth and comply with food safety regulations.

  • Washdown and Corrosion Resistance: Equipment is frequently subjected to high-pressure water and chemical cleaning agents, requiring solenoid valves to have excellent waterproof, moisture-proof, and corrosion-resistant properties.

  • High Speed and High Frequency: Packaging production lines often operate at speeds measured in seconds, so solenoid valves must have an extremely fast response time and an ultra-long cycle life.

  • Precise Control: Whether it's the precise filling of materials or the accurate sealing and cutting of bags, solenoid valves must provide precise pneumatic control.

 

Key Technical Parameters for Food Packaging Valves

 

To address these challenges, when selecting a solenoid valve for food packaging machinery, you must focus on the following key technical parameters:

  • Protection Class (IP): Must reach IP65 or higher to effectively prevent the ingress of water and dust, ensuring stable operation in washdown environments.

  • Corrosion Resistance: External materials such as the valve body and screws should be made of stainless steel or treated for corrosion resistance to withstand the erosion of cleaning agents.

  • Response Time: Recommended to be less than 15ms to meet the production rhythm of high-speed packaging and filling.

  • Cycle Life: Must reach tens of millions of cycles to ensure long-term, continuous operation and reduce downtime for maintenance.

  • Materials: Internal parts that come into contact with the air source must use materials that meet food-grade or non-toxic standards.

 

Recommended AirTAC Solenoid Valve Models for Food Packaging Machinery

 

With its comprehensive product line and strict quality control, AirTAC offers several ideal solenoid valve products for the food packaging industry.

 

1. AirTAC 4V/4A Series (High-Protection Models) Solenoid Valves

 

This is the ideal choice that balances performance with environmental adaptability.

  • Reason for Recommendation: Although a general-purpose series, AirTAC's 4V/4A series can be perfectly adapted to the demanding environment of food packaging by choosing special models with an IP65 or higher protection class. Its robust structure and high flow capacity can reliably control cylinders to complete heavy-duty or high-speed tasks.

  • Typical Applications:

    • Filling and Sealing Machines: Controlling the lifting of filling heads and the grasping and locking of bottle caps.

    • Material Sorting and Conveying: Controlling pneumatic pushers to achieve precise product sorting.

 

2. AirTAC 4M Series Valve Manifold System

 

The valve manifold is a perfect solution for large, complex packaging lines.

  • Reason for Recommendation: On multi-station filling, sealing, or palletizing lines, the 4M Series valve manifold can consolidate multiple valves within a single sealed control cabinet, greatly simplifying external wiring and tubing connections. This not only reduces potential failure points but also complies with hygiene requirements, making it easy to wash down and maintain as a complete unit.

  • Typical Applications:

    • Multi-Station Packaging Lines: Centralizing control of all pneumatic actuators, such as robotic arms, grippers, and pneumatic gates.

    • Robotic Packaging Cells: Serving as the core pneumatic module for a robot's control system, providing stable and reliable control.

 

3. Customized Solutions within the AirTAC 4V Series

 

For critical areas that come into direct contact with food or require frequent washdown, AirTAC can provide customized solutions.

  • Reason for Recommendation: In applications with special material requirements, customized products with special surface treatments on the valve body or the use of stainless steel fittings and screws can be provided. These solutions not only guarantee performance but also further enhance corrosion resistance and hygienic safety.

  • Typical Applications:

    • Direct control of filling nozzles: To ensure precision and hygiene during the filling process.

    • Cleaning systems: Controlling valves that come into direct contact with cleaning fluids to ensure system reliability.

 

The Path to a Complete Hygienic Solution

 

The selection of a solenoid valve is a crucial step in building efficient automated machinery. To ensure optimal performance and adherence to hygiene standards, it is recommended to use AirTAC's full pneumatic solution. From Air Preparation Units (F.R.L.) with stainless steel filters to ensure the purity of compressed air, to stainless steel cylinders and high-protection-class fittings, all components are meticulously designed and tested to achieve perfect compatibility and synergy.

AirTAC solenoid valves, with their exceptional performance, strict quality control, and adaptability to the environment, have earned widespread trust in the food packaging industry. By choosing the right valves, you can inject powerful momentum into your machines, while also ensuring product safety and achieving a dual leap in production efficiency and quality.
