The fixed cone valve has the characteristics of simple structure, light weight, compact layout, flexible operation, convenient maintenance, reliable operation, and small opening and closing force. What are the basic parameters for fixed cone valves? The basic parameters of the fixed cone valve are as follows: Nominal size: DN300~DN3000 Nominal pressure: PN0.6Mpa~1.6Mpa Applicable temperature: -10C ~ 80C Connection form: water, mud, sand, river water, etc. Manufacturing standards: Main material: carbon steel, cast We all know the basic parameters of fixed cone valves of steel, stainless steel and ductile iron. When we use this kind of valves, we should understand that they have these parameters.
