Conclusion
Selecting ball valves by industry requires matching:
-
Body material to corrosion environment
-
Seat material to temperature and chemical compatibility
-
Pressure class to system operating pressure
-
Port type (full vs. reduced) to solids passage and ΔP requirements
Kinko delivers: Industry-specific recommendations within 24 hours. Material certificates and NACE compliance for oil & gas. FDA/USP documentation for sanitary.
