Pneumatic System Design for Packaging Machines: An AirTAC Solenoid Valve Selection Guide

In high-speed, high-precision automated packaging machines, the pneumatic system is the core driving force. As the "brain" of this system, the correct selection of an AirTAC solenoid valve directly determines the machine's efficiency and stability. This article will delve into four key dimensions—function, flow rate, response speed, and environmental adaptability—to guide you on how to scientifically choose the right AirTAC solenoid valve to optimize your packaging machine's performance.

• Function Matching: Common packaging machine movements like clamping, pushing, sealing, and positioning are often performed by single-acting or double-acting cylinders. You should select a two-position three-way (3/2) 3V series solenoid valve for single-acting cylinders or a two-position five-way (5/2) 4V series solenoid valve for double-acting ones. For specific actions that require a stop in the middle, a three-position five-way (5/3) valve from the 4V series is the best choice.

• Flow Rate and Speed: Flow rate is key to determining the packaging machine's cycle time. The valve's effective orifice area dictates the airflow, which in turn affects the cylinder's speed. When selecting a valve, you must match the flow rate to the cylinder's bore, stroke, and desired action time. Choosing from models like the low-flow 4V100 to the high-flow 4V400 ensures the cylinder responds quickly and powerfully, avoiding delays caused by insufficient flow.

• Response Speed and Control Accuracy: In packaging machines that require high-speed, high-frequency switching (like for sealing or sorting), the solenoid valve's response speed is crucial. AirTAC solenoid valves are known for their fast switching, which effectively reduces system latency, ensuring each action is precise and synchronized to boost overall production efficiency.

• Environmental Adaptability and Reliability: Packaging machine environments can be complex, involving dust, moisture, or frequent vibration. AirTAC solenoid valves are built with high-quality materials and precise sealing to resist harsh conditions. For food and pharmaceutical packaging, where cleanliness is critical, you must also ensure the air source is properly filtered and dried to keep both the valve and your products clean.
