What you are ordering
Price is per HVT shutoff valve. All part numbers are separate variants, please select the correct PN from variant options. These HVT shutoff valves are not interchangeable. Different part numbers have different hydraulic parameters, port layout and mounting dimensions. Wrong selection will cause failure of fuel cut-off, engine cannot shut down, unstable running and abnormal fuel control.

When to replace
HVT shutoff valve suffers internal spool wear, seal aging and passage blockage from contaminated fuel after long running hours. Common failure signs: engine cannot shut down normally, random stall, unstable idle, poor fuel cut response. Replace the matched HVT shutoff valve together when abnormal performance appears, and clean fuel oil circuit and check fuel filter condition at the same time.

Strictly confirm the part number and oil port layout before assembly. Do not install HVT shutoff valves of different part numbers interchangeably.
