Forged valves do tend to be better for high-temperature and high-pressure applications. These types of valves are less prone to thermal fatigue because the walls are thinner compared to cast alternatives. Also, forged options have a higher mass, making them mechanically stronger.\r\n\r\n\r\n\r\n\r\n\r\nHowever, there are a few reasons why a forged ball valve may not be best for your application. First, the forging process does create limitations for valve size and shape. Forging generally works better for smaller valves and components. In addition, not every metal is suitable for forging, which limits your options for valve material.\r\n\r\n\r\n\r\n\r\nAdvantages and Disadvantages of Cast Valves\r\n\r\n\r\n\r\n\r\nCast valves are a great option where you need quick turnaround and low-cost valves, as they require less labor to produce. Also, the casting process allows for more complex shapes and valve manufacturing. You also have greater flexibility in material choice, as many types of metals are suitable for casting.\r\n\r\n\r\n\r\n\r\n\r\nWhile cast valves are quite strong and durable when you choose a high-quality manufacturer, there are still some restrictions. For example, the solidification process can create small impurities in the metal. They also are less resistant to high temperatures and pressures compared to a forged ball valve.\r\n\r\n","parent":0,"count":7,"filter":"raw"},{"term_id":3,"name":"gate valve","slug":"gate-valve","term_group":0,"term_taxonomy_id":3,"taxonomy":"post_tag","description":"","parent":0,"count":41,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1928,"label":"Gate Valve"}],"post_tag":[{"value":2176,"label":"cast steel gate valve"},{"value":3268,"label":"Difference Between Cast and Forged"},{"value":3,"label":"gate valve"}]},"yoast_head":"\n
