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
