Pneumatic valve by forging and casting is associated with the size of the pneumatic valve?

pneumatic valve by forging and casting is related to the size of the pneumatic valve? Remember someone said before casting and forging pneumatic valve has a size of connection, a few inches couldn't remember. You know that? In addition, the same caliber of pneumatic valves, forging and casting purposes is there a difference? Size is according to the purpose, has nothing to do with his production process. There is a difference between casting and forging on purpose, but sometimes you can't replace. Affirmation and casting forging pneumatic valve pneumatic valves are distinguished: forging pneumatic valve is mainly used in high pressure, pneumatic valve casting bearing capacity is smaller than forging. Usually consider cost and actual working condition, in addition to the oxygen medium, class and below, are generally 'the following more than casting forging, '. Forging is commonly used in small diameter ( Less than or equal to. Inch) Greater than. Use pneumatic valve casting factory can also do, of course, '' I think generally unnecessary casting forging pneumatic valve can completely meet the requirements the forging is very expensive isn't worth when the forged and large diameter pneumatic valve generally can't do anything. Pneumatic valve by forging and casting and pneumatic valve size has little to do except domestic pneumatic ball valve, the following general pneumatic valve adopts the forging method. But for large diameter high pressure pneumatic valve, the current domestic casting. Different from the pneumatic valve pressure level and use of the temperature, the general high temperature high pressure pneumatic valve pneumatic valve adopts the forgings, ordinary pneumatic valve castings, this is mainly due to the forging and casting density and can withstand the pressure to consider.
