About Series
Shut-off and regulating ALSO Steel Ball Valves with an all-welded body are designed for water in external and internal heating networks at a carrier temperature of up to 200 °C. They are used as well for installation on pipelines and structures on them, transporting liquefied hydrocarbons, oil products and other liquid media, in relation to which the valve materials are corrosion resistant.The range of ALSO Shut-off and regulating Ball Valves includes products with nominal diameters (DN) from 20 to 300 mm, designed for nominal pressure (PN) from 1.6 to 4.0 MPa.
Variants of execution:
Common execution – body made of carbon steel, for use in temperature range from -40 to +200 °С
Cold resistant execution – body made of low-alloy steel, for use in temperature range from -60 to +200 °С
Corrosion-resistant execution – body made of corrosion-resistant steel, for use in temperature range from -60 to +200 °С
