The Stevi AS Y-pattern process valve from ARI-Armaturen is now available with stainless-steel actuation, making it impervious to outside weather conditions, the effects of cleaning liquids and hose-downs, and ensuring its suitability for use in sterile applications.

According to ARI-Armaturen, the Stevi AS is reliable even at high differential pressures and will deliver high power and tight shut-off for up to 1,000,000 strokes.

The self-adjusting stem-sealing system, composed of a spring-loaded PTFE-V-ring unit and a burnished stem with double bearing, ensures a tight seal on closing with zero leakage.
