  • Stellite® grade 21 seat overlays provide excellent durability.
  • Resilient metal seal ring ensures perfect seating force distribution around precision-machined seat circumference.
  • Easily replaceable multi-layered duplex and graphite seal rings.
  • Robust one-piece shaft designed to transfer/maintain torque efficiently.
  • Two-piece packing gland and graphite packing minimize external emission risk.
  • Key secured shaft-to-disc connection for maximum shaft integrity.
  • Heavy duty bearings withstand high pressure loads and wear.
  • Braided graphite bearing protectors prevent dirt intrusion, ensuring constant running torque and valve operability.
  • Internal and external shaft extrusion risk handling complies with international standards.
  • Flange spot facing ensures bolting nut and washer planarity, increasing joint reliability and safety.
  • Open/closed disc references and external disc position indicator simplify installation/removal procedures to API 609.
