The main differences between forged and cast valves lie in their manufacturing process and application scenarios:
Differences in Manufacturing Process
Forged valves are made by plastically deforming a metal billet, resulting in denser metal grains and suitable for high-pressure, small-diameter applications. Cast valves are cast from molten metal and are prone to internal defects, making them suitable for medium- and low-pressure applications with complex structures.
Differences in Application Scenarios
Forged valves are used in high- and ultra-high-pressure systems (such as petrochemical high-pressure pipelines and power plant steam systems, with operating pressures ≥10 MPa), low-temperature/corrosive media, and small-diameter control valves (DN50 and below).
Cast valves are suitable for medium- and low-pressure systems (such as municipal water supply and drainage systems and industrial circulating water systems, with operating pressures ≤6.4 MPa), large-diameter valves (such as DN300 and above), and general operating conditions.
Cost and Performance
The forging process has low raw material utilization and a long processing cycle, resulting in costs typically 30%-50% higher than cast valves of the same specification. Cast valves offer significant cost advantages, especially in large-diameter mass production. However, forged valves offer superior material strength, pressure resistance, and sealing properties.
