Delivery Valve Matching Parts are core precision assemblies for mechanical fuel injection pumps, consisting of delivery valve and valve seat. They control the opening and closing of high-pressure oil passages, eliminate residual pressure in high-pressure fuel pipes and prevent nozzle dripping. They are widely applied to various mechanical diesel injection pumps for trucks, agricultural machinery, construction machinery and marine equipment. Manufactured from high-hardness special steel through matched lapping process with tiny dimensional tolerance and excellent sealing performance, they directly affect fuel supply accuracy and serve as indispensable key parts for injection pump maintenance and overhaul.

🔵 Made of special high-hardness steel, resistant to fuel erosion and abrasion for long continuous operation
🔵 Matched micron-level precision lapping ensures reliable sealing and prevents pressure loss under high pressure
🔵 Effectively cut off residual pipeline oil pressure, avoid nozzle dripping and reduce cylinder carbon deposition
🔵 Abundant specifications fit multiple series of injection pumps with excellent interchangeability
🔵 Group-by-group pressure and tightness inspection before delivery, stable quality and lower maintenance rework rate
