Metallic Sealing Triple Eccentric Butterfly Valve
ZETRIX®
ZETRIX® – the ARI process valve for the most demanding applications.
The disc of the ZETRIX® valve can completely shut off the flow of liquid and gaseous media by means of a 90° open/closed swivel movement. This butterfly valve is versatile, has a long service life and is reliably sealed even under the toughest operating conditions.
