3 Piece Metal To Metal Flanged End Ball Valve

“aira” offers Double-offset wafer type butterfly valve (resilient-seated), available with long or short face-to-face length for use in most common flow control applications. It ensures long service life as the media does not come into contact with the bearing, and due to the wear-resistant, corrosion and infiltration-proof seat with weld overlay. Suitable for use in water distribution, water treatment, pre-treated wastewater, dams, power plants, industry, and pressure management.
