ARI-ZEDOX 122 Double flanged high performance valve - Double offset
Double eccentric – reliable tightness even under challenging service conditions
In contrast to centric butterfly valves, the double-eccentric sealing principle of the new ZEDOX® (double shift of the pivot point) reduces the angle of the disc when it enters into contact with the seat sealing ring and relieves that metallic sealing when opening.
Your advantages:
Functional safety even under challenging service conditions (reliably tight at temperatures from -40°C to
+260°C, PN 10 to PN 40 as well as Class 150)
By reducing the contact pressure and minimizing friction, ZEDOX® offers a long service-life.
The streamlined bearing and shape of the valve-disc stands for a high-energy efficiency.
The protection of the seat-sealing ring against the influence of negative medium flow creates a long
service-life of the ZEDOX®
The low torques garantee a perfect handling.
Easily automated via actuation interface acc. to ISO 5211
ZEDOX® accomplishes leakage rate A acc. to EN 12266, API 598 (bi-directional), soft-sealing (type TS), metallicsealing (type CS) with leakage rate B.
Blow-out proof shaft provides extra safety
Pressure-temperature rating acc. EN 1092, company standard
Approvals acc. Firesafe, ATEX
