XCELDYNE TITANIUM VALVES
TITANIUM VALVES • Superior materials meet all standard Mil. Spec requirements and allow mass reduction, while still maintaining strength in critical areas • Inlet material for maximum strength, ductility & toughness at intermediate temperatures • Fully CNC-machined and ground • 100% inspection of critical dimensions with complete traceability from raw material to complete finished product • Exhaust alloys and processing selected for highest combination of strength, creep resistance, fracture toughness and stability at elevated temperatures • Precision polished for flawless surface finish & reduced carbon build up • Seat run out of .001" or less NOTE: All shelf valves with .3100" stem or larger include steel tip, unless otherwise noted.
