” The Future of Valve Production Testing – Robotic ‘Sniffing’ ”
REVOLUTIONISING VALVE PRODUCTION THROUGH
PRESSURE TESTING
Pressure testing has evolved significantly over the pastdecades, especially after the introduction of Industry 4.0 principles. This critical step ensures that a produced valve is of sufficient quality and integrity to perform reliably after installation and to not cause direct, potentially catastrophic harm. While there are differences between applications, valve types and test standards, one thing is certain: all manufactured valves must be pressure tested to some extent. It‘s simply the law. Manufacturing environments sometimes perceive pressure testing as an interruptive process. It adds no additional value to the materials and,quite frankly, is often a slow and inefficient process requiring a lot of manpower. In fact, Ventil‘s experience with valve manufacturers concludes that 80 to 90% of production bottlenecks are directly related to pressure testing. This waste of potential can be optimised or solved by using the right technology. Let‘s break down and present VENTIL’s ULTRA, the ultimate CNC test bench.

ASME JOURNAL OF PRESSURE VESSEL TECHNOLOGY – ABSTRACT
Helium gas is used for fugitive emission testing of industrial components such as valves. Purpose of these tests is to prevent unintentional and undesirable releases of process gas, from industrial sites, into the environment. These fugitive emissions are direct negative contributors to greenhouse gas emissions and local air quality, and therefore linked to environmental and health and safety rules. The valve industry has standards in place to qualify valves for fugitive emission performance. For instance, ISO 15848-1, classifies valve designs based on emissions, temperature, endurance, and describe the methods for prototype testing.
ISO 15848-2 defines the criteria for production testing. Test methods in these standards, are currently based on Helium gas or Methane gas as the test fluid.
