13 TYPE CODE
17-4PH stem material required to comply API 608 stem strength,
limitations may apply in XG size 8" & 12", see instructions after sign 11.
Balls with coating are used in metal seated valves.
Max temperatures for coatings:
- Hard Chrome (HCr): 450 °C
- Tungsten carbide (WC-Co): 450 °C
- Chrome carbide (CrC/CrC-LF): 600 °C
If seat coating is Chrome Carbide, CrC-LF, then use Chrome Carbide, CrC as
ball coating.
EN/ISO bolting materials are obsoleted. ASME bolting materials can be used in
EN rated valves.
* Bolting materials for stainless steel body
** Bolting materials for carbon and low alloy steel body
