Description
Product Overview
The control valve kit is the core component for the electromagnetic drive control of the injector. It relies on the valve body's oil passage,分流 valve plates， and sealing steel balls to precisely regulate the timing and single-shot fuel injection volume of the high-pressure fuel injection. Under long-term working conditions in construction sites， mining areas， and those subject to high-temperature and heavy-load conditions, where diesel impurities erode the equipment, the valve body's oil passage may get clogged， the sealing of the steel balls may fail， and the valve plates may wear out. This can lead to deviations in injection timing， imbalance in fuel supply among cylinders， reduction in overall machine power， and a significant increase in fuel consumption. This product is pre-assembled in three pieces and undergoes comprehensive testing for high-pressure resistance， flow accuracy， and sealing performance upon leaving the factory. The entire machine can be maintained without the need to disassemble and select spare parts. It is suitable for maintenance and replacement of fuel injection systems in light trucks， large excavators， agricultural machinery， and diesel generator sets.
Unique core advantages of the individual product
Three-piece integrated assembly， completing single-cylinder maintenance in one step
Each complete set includes a circular main control valve body， multi-hole flow-dividing valve plates， and high-precision sealing steel balls. With just one set， the control valve of a single injector can be replaced， eliminating the cumbersome steps of separately purchasing and verifying various small parts. This significantly shortens the maintenance time.
Overall nitrogenized and hardened alloy steel material， resistant to wear and high-pressure， reducing internal leakage
Both the valve body and the分流 valve plates are processed from high-hardness alloy steel， with surface nitrogenization hardening + mirror finish grinding treatment. Under long-term high-pressure diesel erosion， they are less likely to develop scratches or deform， maintaining stable oil passage dimensions， effectively blocking internal leakage of high-pressure fuel， and ensuring stable output of track pressure.
Multiple specifications of layered flow-dividing oil holes， linear and smooth oil pressure adjustment
The valve body and valve plates are distributed with multiple sets of precise flow-dividing holes. The high-pressure fuel is evenly divided and circulated， with smooth changes in oil pressure without sudden fluctuations， eliminating acceleration jolts， uneven power at high and low speeds， and reducing fuel atomization and carbon deposits in the cylinder and black smoke in the exhaust.
High-precision solid sealing steel balls， quickly locking the oil path and preventing leakage
The matching high-precision bearing steel balls are in close micro-metric fit with the valve seat center hole for sealing. In the event of power failure， the high-pressure oil path is quickly cut off to prevent fuel from dripping into the cylinder during shutdown， resolving difficulties in cold start and excessive carbon buildup.
Micro-hole non-asperity precision processing， less likely to get stuck or clogged
All flow-dividing throttling micro-holes adopt mirror surface micro-hole precision grinding technology， with smooth inner walls without processing burrs. Diesel gums and tiny impurities are less likely to adhere and accumulate， reducing the probability of injector sticking and extending the lifespan of spare parts. Applicable scenarios
This product is suitable for light/heavy-duty diesel trucks with electronic fuel injection common rail system, mining excavators, wheeled loaders, fixed diesel generators, and diesel equipment with fuel injection systems in construction sites and mining areas that operate continuously at full load, in high-temperature and dusty conditions, with a large amount of fuel impurities. It is applicable for major overhauls of diesel equipment's injection systems.
