- Optimum safety: advanced protection systems for operators and tested equipment.
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.

Pressure testing methods
Pressure testing is essential for verifying the performance and safety of products in real-life conditions. At LF Technologies, we use advanced methods to meet your specific needs:
- Hydrostatic testing: Assessment of the strength and watertightness of materials using pressurised water.
- Pneumatic testing: Use of compressed air to detect leaks with increased sensitivity.
- Cyclic pressure testing: Analysis of the endurance of products subjected to repeated pressure variations.
- Burst tests: Determining the maximum strength limits of pressure equipment.
These methods enable rapid and accurate detection of anomalies, guaranteeing compliance with the most stringent standards. Thanks to our test benches, your products will benefit from rigorous control while optimising development and production processes.
