For many years, the idea of the production of Gate valve from the PE material has been discussed between valve manufacturers and engineers.
Some unsuccessful tries have been made on this way. However, the implementation of this idea is believed to be impossible because of PE olding material specification is assumed as not compatible with the principle of the gate valve.
Since 2005, TEGA R & D group has entered into an intensive effort to realize this dream, and attempted numerous calculations, analysis and tests on this way.
At the end of six-year period, TEGA has managed to reach to the needed technical criteria and has succeed the first in the world. Even the biggest manufacturers gave up to dream on this way TEGA Engineering R & D Group feel right proud of their success.
|Complete PE body and outlets||No need for flange or mechanical connections|
|High resistance to corrosion and chemicals||Low weight compared with metal valves|
|High resistance to break||High flexibility|
