Description
- Robust and fire-resistant all-metal construction.
- 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.
- Spiral wound gaskets, seal and packing rings replaceable with no special tools.
