Product Description
Delivery valve
The varieties of delivery valve couples produced by Huahui Oil Pump and Nozzle Company include: BQ series, No. I series, No. II series, A series, AK series, AD series, P series, and high-pressure common rail series, with diameters ranging from 5 to 9 mm. The product can meet the requirements of various diesel engine supporting oil pumps.
The delivery valve couple is a key component of the fuel injection system, which is accurately paired with the delivery valve and the delivery valve seat. Made of high-quality steel, the sealing surface is ground with high precision, and the sealing accuracy can reach ±0.001mm. Accurately control fuel flow during work to prevent fuel backflow, ensure stable injection pressure, and ensure efficient engine operation.
Overview
The F832 Delivery Valve Assembly is a high-precision component designed for diesel fuel injection systems, specifically for inline injection pumps. Its primary function is to regulate the flow of fuel from the plunger barrel to the injector nozzle and prevent fuel backflow after injection. By ensuring stable pressure and clean fuel cutoff, the F832 helps improve fuel atomization, reduce emissions, and maintain consistent engine performance.
Manufactured using premium alloy steel and advanced heat treatment techniques, the F832 is engineered to meet the demands of high-pressure, high-speed diesel engines, providing both durability and precision.

Can you design the equipment according to our size?
Yes
What is the function of the F832 Delivery Valve Assembly?
It regulates fuel flow from the injection pump to the injector and prevents fuel from returning to the pump after injection, improving pressure stability and engine performance.
What are signs of a faulty delivery valve assembly?
Common symptoms include hard engine starting, uneven idling, increased fuel consumption, black smoke, or injector dribbling.
Can I replace the F832 delivery valve myself?
While possible, installation requires precision and cleanliness to avoid contamination or pressure issues. It is recommended to have it installed by a qualified technician.
How long does the F832 typically last?
When used with clean diesel fuel and regular maintenance, it can last over 2,000–3,000 operating hours, depending on engine load and usage conditions.
