New helium leak test system

It has been installed a new helium leak test system for high-pressure valves used on LPG/methane automotive equipments.

The high accuracy required by the technical specifications (detection of leak rates in the range of 1E-6 mbar l/s) has led us to choose the technique of the trace gas detection under vacuum chamber. Moreover, the high test pressure (up to 300 bar) has required the implementation of an extremely sophisticated pneumatical circuitry.

The further requirement of opening and closing the valve during the test, measuring in the meantime the drive torque, has made the application even more complex.
