In this video, endurance test by NUPI on the new PP-RCT ball valves. The test consists of 20,000 open/close cycles, with test pressure of 10bar and temperature +20°C/+95°C. Endurance testing refers to tests typically done to find out whether an application can withstand the processing load it is expected to have to endure for a long period. They are used mainly to measure the response of a tested element under potential simulated conditions for a specific period and for a certain threshold. Observations recorded during the endurance test are used to further enhance the parameters of the tested element.
