⚙️ 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
