Material is not the same, high temperature ball valve generally used alloy valve body, this material is high temperature, corrosion resistance; Ordinary steel ball valves and copper ball valves are only rust proof, while the thermal deformation is relatively large.

1、The main difference between high temperature ball valve and normal temperature ball valve manufacturing process is different.

2、Material is not the same, high temperature ball valve generally used alloy valve body, this material is high temperature, corrosion resistance; Ordinary steel ball valves and copper ball valves are only rust proof, while the thermal deformation is relatively large.

3、The sealing ring material is also different: generally normal temperature ball valve is soft seal seat; High temperature ball valves are hard sealed (metal or mechanical carbon and ceramic, etc.), and the inner material of the valve is better than the soft seal.

4、Material treatment: generally normal temperature ball valve lathe processing can be directly into the assembly; High temperature ball valve also after treatment (because different material processing process is not the same, such as nitriding, spraying and so on).

5、Assembly: general room temperature ball valve to get parts can be assembled; High temperature ball valves need to grind the ball core and seat, this process is also very critical, the size of the leakage depends on grinding.
