Double Flange Butterfly Valve
Description
Double-offset flanged butterfly valve, available with long or short face-to-face length for use in most common flow control applications. 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.
