“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. 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 water distribution, water treatment, pre – treated waste water, dams, power plants, industry and pressure management.
