The HELANTEC valve is the key to success for correct pressure balancing, and for maintaining your assured characteristics for the IG unit.
With our ISO-Altimeter PROFESSIONAL pressure balance system the IG unit is prepared in production in such a manner that it is flat at the higher altitude or lower altitude of the installation site. In this regard the HELANTEC valve is used for safe sealing during and after the pressure balancing.
Naturally the leak-tightness and material compatibility are tested and certified. Consequently the HELANTEC valve is used instead of the well-known sleeve plug system for manual gas filling technology.
More than 1.4 million HELANTEC valves are already in use around the world. Rely on this proven and progressive technology.
