Introduction:

First, the main difference between high temperature ball valve and the ball valve manufacturing process is different;

Second, the difference between the seal: The general temperature ball valve is soft seal seat; high temperature is a hard seal (metal or mechanical carbon and ceramic, etc.), and the valve trim material is better than the soft seal;

Third, the material handling: After normal temperature ball valve lathe can be processed directly into the assembly; high temperature ball valve also have to be dealt with (because of different materials processing technology is not the same, such as nitriding, spraying, etc., here is not to say in detail );

Fourth, the assembly: After the ball at room temperature to get the parts can be assembled; high temperature ball valve needs to be ground ball and seat, this sequence is also critical, the size of the leakage by grinding.
