DIN Standard GG25 Cast Iron Globe Valve

There are significant differences between cast iron globe valves and cast steel globe valves in terms of materials, pressure ratings, applicable ranges, and prices. It is very important to choose the appropriate material and type of globe valve according to specific application requirements and working conditions.

Cast iron globe valves are made of cast iron material, while cast steel globe valves are made of cast steel material. Cast iron materials usually have higher hardness and brittleness, while cast steel materials have higher strength and toughness. Due to the higher strength of cast steel materials, cast steel globe valves are usually suitable for applications with higher pressure levels and can typically withstand greater pressure. Due to the high brittleness of cast iron materials, cast iron globe valves are usually suitable for low-pressure and general industrial applications, while cast steel globe valves are suitable for applications under higher pressure, high temperature, and special working conditions. Due to differences in manufacturing processes and material costs, cast steel globe valves are typically more expensive than cast iron globe valves.
