Meggitt Whittaker CDP Purge & Vent Valves
Meggitt valves are highly accurate, precise and reliable, providing gas turbines with the consistent control required to perform efficiently at peak performance. Fast and resilient, Meggitt’s hot air purge and blow-off valves optimise important operational procedures like fuel purging and load shedding, increasing safety, efficiency and reliability.
Often fitted in pairs to provide dual redundancy, they are highly reliable and very fast-acting. Compressor bleed air is used to perform many vital ancillary gas turbine functions, including combustor fuel purging. Many industrial gas turbines are ‘dual fuel’ running on diesel as well as natural gas. When switching back to gas, even small amounts of residual diesel would quickly ‘coke up’ the fuel delivery tubes and nozzles if the combustor was not first cleaned — or ‘purged’ — using hot, high pressure bleed air from the turbine’s compressor.
Meggitt’s sleeve-style, hot air purge valves control this important process with exceptional reliability, speed and precision.
- “Meggitt purge valves last for many years, despite the 600°C (1100°F) operating environment”
- “Fast full-stroke performance is achieved by carefully balancing pressure forces”
- “Special contouring and material sculpting helps keep the actuators cool”
