Leakage and functional testing of valves and fittings

Leak testing and leak detection procedures must be performed to maintain the integrity and effectiveness of valves, fittings, and faucets. Leaks can negatively impact efficiency, drive up energy costs and, in the case of hazardous materials, create potentially dangerous circumstances.

When leak testing fittings and valves, manufacturers are faced with several challenges:

Leakage testing is often combined with functional tests. Diaphragm tests, valve movements, check valves, pre-setting, latching test or spring forces are some of the challenges that must be solved in the production of these parts. Manufacturers must address high product diversity with sometimes more than 1,000 test item variants needing to be tested on one system, as well as long production times. Different tests may have to be combined, some with very high tightness requirements, due to variable operating media and areas of application.

Eliminating leak defects in faucets, fittings, and valves

Solutions can include different feeding methods such as robotic handling with changing grippers or a light table with camera positioning. It is not uncommon for leak testing to combine several measurement methods, for example the helium vacuum integral method for external leakage, coupled with flow or volume measurement, or other special methods for functional and assembly verification. In addition to these methods, there are also various tools and devices that can be used for leak testing and leak detection, e.g. leak detection fluids and special sensors and cameras.
