FIRST IN THE WORLD
For many years, the ideal of production of Gate Valve from PE material has been discussed between valve manufacturers and engineers.
Some unsucessful tries have been made on this way. However, the implementation of this idea is believed to be impossible because of Pe molding material specification is assumed as not compatible with principle of the gate valve
Since 2005, TEGA R&D group has entered into intensive effort to realize this dream, and attempted numerous calculations, analysis and tests on this way. At the end of six-year perion, TEGA has managed to reach to the needed technical criteria and succeed as the first in the world. Even the biggest manufacturers gave up to dream on the way. TEGA engineering R&D group feel proud of their success.
165 hour and 1000 hour aging tests according to EN12201-4 are the basis of TEGA PE gate valves 60 years lifetime warranty
Up to 60% of leakage occurs around valves and mechanical joints
