Features & Benefits

01 – LINED PLUG VALVES : ”aira” lined plug valves are made to with stand 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 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 attack due to permeation.

03 – LOCKED-IN LINER : ”aira” Lined plug 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 blow out. The liner is spark tested in accordance with ASTM D5126 SPEC.

04 – CAVITY-FREE DESIGN : By design, Lined Plug Valve are cavity-free both in open and closed positions – No particle accumulation/-Ideal for corrosive slurry applications.

05 – UNMATCHED SUPERIOR SEALING. BI-DIRECTIONAL ZERO LEAKAGE : Primary sealing by PFA eith PFA 360°C contact with the lined body. Leaving absolutely no chance for In – line or atmospheric leakage. This gives highest level of sealing when compared to any other valve design. ( When compared with conventional ball valve, butterfly valve, gate valve, globe valve designs.)- Tight shut – off/Compression seal ( Upstream & downstream )/- Sealed at both plug & stem
