What are the differences between ordinary stainless steel ball valves and high temperature ball valves?
The main difference between high temperature ball valve and normal temperature ball valve is different from the manufacturing process,
Material handling: general lathe after valve at room temperature end can be directly into the high temperature ball valve assembly; even after (because of different material processing technology processing are not the same, such as nitriding, spraying and so on, there is no detailed say)
Sealing difference: general room temperature ball valve is a soft sealing seat; high temperature is hard seal (metal or mechanical carbon, and ceramic, etc.), and the valve material is better than the soft seal,
Assembly: general room temperature ball valve to get the parts can be assembled after; high temperature ball valve grinding ball core and valve seat, this order is also critical, the size of the leak by grinding
