Leak and pressure testing
The principle of leak testing is based on the creation of a pressure or vacuum condition to observe the reaction of the component or system under test. This method effectively detects even the smallest faults or leaks, which could not only lead to malfunctions but also compromise safety. Testing is crucial in sectors such as aeronautics, the automotive industry and hydraulics, where the slightest leak can have serious consequences.

Our key test bench for leak testing – LeakRTS
Product tested
Ball valve and valve extension. A valve is a plumbing device that is operated to regulate a flow. There are several types of valves. The ball valve is either a shut-off valve to stop the flow of water, or a flow control valve. LEAKRTS is specially designed to test these types of valves, offering a reliable method of detecting leaks, even at extremely low rates. It can also simulate an adjustable clamping force corresponding to the tightening of the valve flanges, ensuring an accurate simulation of real operating conditions.
PROBLEMATIC ISSUES
- Be able to measure extremely low leakage rates.
- To be able to simulate an adjustable tightening force corresponding to the tightening of the valve flanges.
- Enables leak testing of a wide range of valve sizes.
- The system must be compact and transportable, with good ergonomics.
Our leak test benches are designed to meet these requirements, offering complete and effective solutions for all your leak testing needs.

The importance of leak testing
Pressure leak testing is a critical process used to ensure the integration and performance of components such as valve cartridges, hydraulic valves, piping and turbines, as well as hydraulic systems; By subjecting them to controlled pressure or vacuum conditions, these tests can accurately identify any potential leaks or failures. The aim is to prevent any risk that could compromise the functionality, safety or durability of the systems tested. They are therefore essential in sectors where reliability is non-negotiable, such as aerospace, automotive and medical equipment.
The effectiveness of these pressure leak tests relies on the use of complex detectors and advanced techniques to measure the leak rate. The methods used include controlled pressure dropwhich measures the pressure reduction in a closed system,gas accumulationtechnology, which is often used in conjunction with tracer gases to locate leaks, and ultrasonic technology, which detects the sounds emitted by pressurised gas or liquid leaks.
Each method is specially chosen and adapted to the specific characteristics of the product being tested, whether it’s a small hydraulic component or a large industrial plant.
These tests are not limited to detecting existing problems; they also play an important role in predicting and preventing future failures. This contributes to better maintenance planning and a reduction in unexpected downtime. By understanding and controlling the risks associated with leaks and seal failures, manufacturers can ensure superior product quality and comply with strict safety and quality regulations. Pressure leak testing is therefore an essential investment in the quality and long-term reputation of any product or system.
