Woodward 3180-050, Relief Valve Plunger - Tempest PMA
Tempest AG3180-050-PMA
The Tempest AG3180-050 (Woodward OEM 3180-050) is an FAA-PMA replacement relief valve plunger for Woodward applications.
- Acts as the primary moving element in the relief valve, opening and closing against spring force to maintain target internal oil pressure.
- Helps protect internal governor components by controlling peak pressure during transient conditions such as rapid power changes or cold oil operation.
- Often replaced during overhaul if wear, scoring, sticking, or contamination has affected relief valve response or pressure stability.
This plunger is intended for aviation constant speed propeller governor maintenance and overhaul, where correct governor oil pressure directly affects propeller response and RPM stability.
Installation notes
Always refer to the applicable aircraft and governor maintenance manual for complete installation procedures.
- Inspect the relief valve bore and related components for scoring or contamination that could cause sticking.
- Set and verify relief valve pressure per the approved Woodward maintenance procedures after installation.
