Features that Add Value:
- Body Guided disc in globe valves (all sizes/classes) provides disc stability and avoids vibration of the disc-disc nut assembly
- Non-rotating rising stem design in globe valves (2” and above) yields a 20-30% reduction in valve torque vis-à-vis the Rotating rising stem globe valves
- In-situ seat design in all globe valves
- Inconel overlay cladded option available for economical solutions
Versatile Solutions:
- Y-Globe, Bellows-sealed, FBE/ Fusion-bonded Epoxy Lined, Steam-Jacketed
- ValvTrac™ RFID tagging offered for reliable digital traceability
Stainless Steel Corrosion-Resistant Globe Valves
Special Features:
