What is the difference between high temperature ball valve and ordinary ball valve

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

2. the material is not the same, high temperature ball valve generally use alloy body, this material high temperature, corrosion resistance; ordinary steel ball valve and copper ball valve is only rust, while the thermal deformation is relatively large.

The material of the 3. sealing ring is also different: the general normal temperature ball valve is a soft sealing valve seat; The high temperature ball valve is a hard seal (metal or mechanical carbon and ceramic, etc.), and the material of the valve inner is better than that of the soft seal.

4. material processing: general normal temperature ball valve lathe processing can be directly into the assembly; high temperature ball valve has to be processed (because the process of different materials is not the same, such as nitriding, spraying, etc.).

5. assembly: general normal temperature ball valve can be assembled after getting the parts; High temperature ball valve needs to grind the ball core and valve seat. This sequence is also very critical. The leakage depends on grinding.
