## ⚙️ Key Features

-   0.027216 kg valve seat
-   Supersedes 468729 and 469331
-   469331 was previously listed as a relief valve seat
-   70 applications across six engine series

## 🔌 Function

Gives the relief valve a machined seat to close against, so the valve holds pressure until it is meant to lift.

## ⚠️ Common Signs of Failure

-   Pressure reading low or unsteady because the valve will not hold
-   Seat face ringed, pitted or bruised
-   Valve not sealing when pushed onto the seat by hand
-   Debris marks across the seat face

## 🛠️ Service Notes

-   Cover 469465 and compression spring 470291 also supersede 468729, so the old single number covered the whole relief valve and the pieces are now ordered separately
-   Renew the spring at the same time as the seat - a bedded-in spring will not hold a new seat to pressure
