A GGG40 Control Valve is made from nodular cast iron, specifically the GGG40 alloy, which is characterized by its predominantly ferritic structure. This material is known for its excellent machinability, good impact resistance, high electrical conductivity, and good elongation properties, as well as its magnetic permeability. However, GGG40 cast iron cannot be welded. The valve utilizes these properties to provide reliable performance in various industrial applications where these characteristics are beneficial.
