The TUNPROTEC® Zone Valve Station Model C-NHV & C-NHV-A Valves have successfully been endurance tested with 1000 operations cycles and have furthermore been tested to corrosion tests and other such component tests described in CEN/TS 14972. Further, the valves have been evaluated in accordance to EN ISO 13849-1 and EN ISO 13849-2 to find MTTFd (Mean Time To dangerous Failure) and it was found that the valves can withstand for 150 years before the first dangerous failure will occur.
