Solenoid Valve Selection Guide Based on Industry Application Characteristics

Solenoid Valve Selection Guide Based on Industry Application Characteristics

In modern industrial automation, the solenoid valve is a core control component, often called the "brain of the pneumatic system." Its selection directly determines the precision, stability, and overall performance of equipment. However, the requirements for solenoid valves vary greatly across different industries. To ensure a system is efficient and reliable, it's essential to deeply consider the unique environment and requirements of its application.

This article aims to provide a comprehensive solenoid valve selection guide to help you choose the most suitable AirTAC product based on your industry's characteristics.

 

I. Core Technical Parameters of Solenoid Valves

 

Before selecting, you first need to understand the key technical specifications of a solenoid valve:

  • Working Type: Common types include 2/2-way, 3/2-way, 5/2-way, and 5/3-way valves, which control airflow direction to suit different cylinders or actuators.

  • Nominal Diameter (G): The size of the valve's port, which directly affects the flow rate and must be matched to the cylinder's size.

  • Cv Value (Flow Capacity): Represents the valve's flow rate. A larger Cv value means faster flow, suitable for large or high-speed cylinders.

  • Working Pressure: The pressure range within which the valve operates normally.

  • Response Time: The time required for the valve to complete a switch after receiving an electrical signal. This is crucial for high-speed applications.

  • Protection Class (IP): Measures the valve's resistance to dust and water. For example, IP65 means it is dust-tight and can withstand low-pressure water jets.

  • Endurance (Life Cycle): An important indicator of reliability, usually measured in millions of cycles.

 

II. Solenoid Valve Selection Based on Industry Characteristics

 

The specific demands of different industries determine the focus of solenoid valve selection.

 

1. Automotive Manufacturing

 

Industry Characteristics: Fast-paced production lines, high-frequency cycles, and harsh environments (welding spatter, oil, dust).

Selection Focus: Extreme durability, fast response, and a high protection class.

  • Technical Parameters: Requires products with a high-frequency response (<20ms), high protection class (IP65 and above), and a life cycle of tens of millions of cycles.

  • AirTAC Product Recommendation: 4V/4A Series Solenoid Valves.

    • Reason for Recommendation: Specifically designed for high-intensity industrial environments, they effectively resist dust, oil, and vibration. Their spool uses a special process to ensure excellent stability and an ultra-long life under high-frequency switching.

    • Product Advantages: High-flow design can quickly drive large cylinders; multiple protection measures ensure reliable operation in harsh environments; various wiring methods and voltages are available for easy integration.

 

2. Electronics and Semiconductor Industry

 

Industry Characteristics: Cleanroom environments, compact spaces, and a need for extremely high positioning precision and repeatability.

Selection Focus: Ultra-high precision, compact design, and low power consumption.

  • Technical Parameters: Miniaturized size, short response time, and low heat/noise during operation.

  • AirTAC Product Recommendation: 3V1/2V0/2V00 Series Miniature Solenoid Valves.

    • Reason for Recommendation: The precise manufacturing process allows for millisecond-level accurate control, while their compact size and low power consumption perfectly match the needs of robotic arms and high-density integrated equipment.

    • Product Advantages: Small size and light weight for easy installation in confined spaces; fast response speed ensures the precision of high-frequency pick-and-place operations; low power consumption design reduces heat generation.

 

3. Food Packaging and Light Industry Textiles

 

Industry Characteristics: Strong production continuity, high-frequency operation, high hygiene standards for food, and high precision/speed requirements for textiles.

Selection Focus: High reliability, fast response, and easy maintenance.

  • Technical Parameters: Requires products with fast response and simple maintenance. For the food industry, corrosion resistance and easy-to-clean materials are crucial.

  • AirTAC Product Recommendation: 4V/4A Series, 5/2-way, and other highly reliable solenoid valves.

    • Reason for Recommendation: Their stable performance and ultra-long service life guarantee the continuous, high-intensity operation of production lines, reducing downtime caused by valve failure.

    • Product Advantages: Excellent reliability ensures the equipment works for long periods without interruption; fast switching speed meets the needs of high-speed packaging and cutting; modular design facilitates maintenance and expansion.

 

4. Medical Devices

 

Industry Characteristics: Life safety is a concern, requiring extremely high reliability, quiet operation, low power consumption, and miniaturization.

Selection Focus: Ultra-long life, high precision, silent operation, and miniaturization.

  • Technical Parameters: Stable response, low power consumption, and low noise.

  • AirTAC Product Recommendation: AirTAC's miniature solenoid valves designed specifically for the medical industry.

    • Reason for Recommendation: These valves are designed to fully consider the unique nature of the medical environment, ensuring every action is precise and reliable while minimizing noise and power consumption so as not to disturb patients.

    • Product Advantages: High reliability ensures the equipment won't fail at critical moments; silent operation improves patient comfort; miniaturized design is suitable for integration into portable or diagnostic devices.
