How it works :
Vibrations may occur at low flow rates. These vibrations are generated by a lateral movement of the obturator. Until now, it has not been possible to avoid this effect without affecting the hydraulic characteristics of the fluid. Thanks to a unique guiding system with an interlocking obturator, any possibility of obturator movement is eliminated, optimally maintaining hydraulic characteristics and eliminating vibrations. By providing this movement-free guide, scale deposits and vibrations are avoided, guaranteeing faultless, silent operation for years to come.
