It is used to determine the linning continuity and detect any possible holyday or porosity through the application of high voltage.
Spark is generated in case of defect, so that the area to be relined again is detected, thus guaranteeing the protection and the operability of the valve.
These tests are performed on 100% of our #Diaval diaphragm valves prior to assembly.
