Features & Benefits

01 – LINED CONTROL VALVES: ” Aira” lined Control valves are made to withstand harsh corrosive and abrasive media with much higher sealing capacity than all other quarter turn valves to perform superiorly even after prolonged use. This makes it ideally suited as a more economical choice in the long run. Made to perform in vacuum as well as in high-pressure application.

02 – CORROSION PROTECTION: Low porosity FEP/PFA (Perfluoroalkoxy) as standard liner. All cast parts have an epoxy-based coating for added protection from corrosion attacks due to permeation.

03 – LOCKED-IN LINER: ”aira” Lined Control valves feature an unpigmented virgin FEP/PFA lining applied by Transfer Moulding and locked into castings by machined dovetail-shaped recesses in body casting and cast holes. This resists shrinkage and blowout. The liner is spark tested in accordance with ASTM D5126 SPEC.
