Features
- Non-rubbing 90-degree rotation and metal-to-metal torque seating provide bi-directional zero leakage tightness to ISO 5208, EN 12266-1 and API 598.
- Bolted extended bonnet protects packing from cryogenic service temperatures.
- Forged one-piece Nitronic® 50 metal seal ring ensures high corrosion resistance and keeps important mechanical features at low temperatures.
- Buttweld top entry design allows access without removing the valve body from the line.
- Stellite® grade 21 overlay seats are maintenance-free.
- Robust and fire-resistant all-metal construction.
- Spot-faced flanges ensure maximum joint-to-pipe integrity.
- 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.
