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

Special Features:Stainless Steel Corrosion-Resistant Globe Valves
