Vanessa-K-Series 30000 Cryogenic Powered Actuator

Vanessa Series 30,000 Cryogenic Triple Offset Valve with Powered Actuator

Descrizione del prodotto

The Vanessa Series 30,000 Cryogenic Triple Offset Valve is a virtually maintenance-free valve with tightness, operability and torque demand unaffected by cryogenic conditions and severe temperature fluctuations. The valve comes complete with powered actuator, configurable by power source, size, function and more.

Funzionalità

Vanessa Series 30,000 Cryogenic Triple Offset Valve
  • 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.
Emerson Powered Actuator
  • Direct mounting to all Keystone butterfly valves and ball valves.
  • Valve connection compatible with Keystone (imperial and metric) and ISO 5211.
  • Double Rack and Pinion design nullifies side loads on the pinion shaft, minimizing bearing wear and extending life.
  • Optimized product flow with standard mounted travel stops for valve position adjustment in open and close position (+/- 5° at each end).
  • Anodized aluminium body with electrostatic powder coating (ESPC) finish provides durable protection against corrosive environments.
  • Double acting and spring return versions available for cost effective and safe operation.
  • Up to 12 individual springs offer flexible torque range for both ball as butterfly valves.
  • Pre-compressed spring design and anti-blowout drive pinion means safe maintenance and operation.
