In many industrial applications, especially those involving sensitive processes, medical equipment, or hazardous materials, having reliable, leak-free systems is a must. The article, “An Overview of Leak Detection Testing” from our partner Clippard, explores the importance of low-leak valves and the testing methods used to ensure their performance. The article explains that leaks in a valve are quantified by a leak rate, and outlines two primary testing methods: pressure decay testing and helium leak detection.

Pressure decay testing is a straightforward method that checks a valve’s seals by measuring its ability to hold pressure over a period of time. While it can confirm a valve is “bubble tight,” its overall sensitivity is limited. For more precise results, Clippard uses helium leak detection. This more advanced method employs a mass spectrometer to detect tiny amounts of helium that might pass through a valve’s seals in a deep vacuum. This approach provides a more accurate and specific leak rate, making it suitable for applications where even the smallest leak can have a significant impact.
