Bosch Coded Delivery Valve is a precision matching part built into Bosch series fuel injection pumps. With standard codes for accurate matching of corresponding pump models, it controls the opening and closing of high-pressure fuel, eliminates residual pressure in fuel pipelines and prevents post-injection fuel dripping. It is widely used in traditional mechanical diesel injection pumps for trucks, construction machinery and agricultural machinery. Manufactured from special wear-resistant steel via micron-level matched lapping, it features strict dimensional tolerance and stable oil pressure control, serving as a core component for fuel injection pump maintenance and overhaul.

🔵 Exclusive coding mark with clear model classification, precisely matching various series of Bosch injection pumps
🔵 Micron-level matched lapping delivers outstanding sealing performance to avoid pressure loss under high pressure
🔵 Premium wear-resistant alloy steel withstands fuel scouring for prolonged service life
🔵 Stably cut off residual oil pressure, prevent nozzle dripping and reduce engine carbon deposition
🔵 Group-by-group tightness test before delivery, high interchangeability for convenient pump assembly and debugging
