Description
This valve is part of the auxiliary pneumatic and cooling systems that support the operation of the RB211 gas generator. In industrial RB211 installations (such as power generation or gas compression packages), “Davis” type valves are commonly associated with regulating airflow for module cooling or managing air pressure/venting requirements within the auxiliary compartments of the turbine package.
Key Specifications
- Component Type: Davis Type Vent Valve
- Part Numbers: * SV2689-1 (Main Identifier)
- LW20136 / LW16679 (Associated Part Numbers/Serial References)
- Application: RB211 Industrial Gas Turbine packages (e.g., RB211-24G, DLE variants).
- Function: These valves typically manage the routing or venting of cooling air for engine modules and are critical to maintaining the thermal environment within the engine enclosure.
Context for Maintenance
If you are currently handling or sourcing this valve, note the following:
- System Integration: These valves are often found referenced in the “OEM Volume” manuals for industrial RB211 installations, particularly regarding module cooling air interfaces.
- Maintenance Note: As a precision pneumatic component, ensure that any seals or internal components are inspected for oxidation or degradation, especially if the unit is “New Old Stock” (NOS), as storage conditions over time can affect the integrity of internal elastomer seals.
- Compatibility: The part numbers LW20136 and LW16679 are generally treated as interchangeable or sequential revisions within the manufacturer’s parts list for the SV2689-1 assembly. Always verify the specific revision level against your turbine’s Illustrated Parts Catalogue (IPC).
