Vanessa Series 30,000 Cryogenic Triple Offset Valve

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.
