The next generation LM air valves by Meggitt

In July & August 2016 GE had released a service bulletin & letter recommending replacement of existing 2.5″, 4” and 6″ Honeywell CDP, VSV and Thrust Balance valves on GE LM engines.  The OEM recommendation was the use of Meggitt butterfly bleed air valves for reasons Meggitt Bleed Air Valve 6 inch L59092P03 - C424065-7of improved reliability.

These new OEM recommended Meggitt valves are fully interchangeable with your current Honeywell bleed air valves in form, fit & function and they fully comply with the OEM specifications on the flow versus stroke requirements.

Major Oil & Gas companies, power producers and process industries have already started valve exchange programs for their entire LM fleets.

All three types of the OEM recommended Meggitt valves are normally on stock at the VBR Turbine Partners warehouse in Elst for immediate availability to LM1600, LM2500/+, LM6000 and LMS100 owners and operators worldwide.
