Description
Product Overview
The control valve kit is the core of the electromagnetic control of the electronically controlled fuel injector. It relies on the valve body oil passage,分流 valve plate， and steel balls to respond to the ECU's electrical signals， precisely controlling the timing and single-shot fuel injection volume of the high-pressure fuel injection. After long-term heavy-duty mining operations and exposure to high-temperature diesel impurities， the oil passage may become clogged， the steel balls may not seal properly， and the valve plates may wear out. This can lead to irregular fuel injection timing， imbalance in fuel supply among cylinders， a decline in overall engine power， and a sharp increase in fuel consumption. This product comes with a complete set of valve body，分流 valve plate， and sealing steel balls pre-installed. It undergoes comprehensive testing for flow accuracy， high-pressure leakage， and electromagnetic response upon leaving the factory. It is suitable for maintenance and replacement of fuel injectors in heavy-duty trucks， mining excavators， and large diesel generator sets.
Unique Core Features of the Single Product
Three standardized sets of components are provided for one-step repair and assembly.
Each complete set includes a circular main control valve body， multi-hole flow-diverting valve plate， and high-precision sealing steel balls. With just one set， the control valve of a single fuel injector can be replaced， eliminating the cumbersome process of separately purchasing scattered parts and verifying models， and significantly reducing maintenance time.
The overall material is nitrided and hardened alloy steel， which is wear-resistant and resistant to high pressure and is less prone to scratching.
Both the valve body and the分流 valve plate are machined from high-hardness alloy steel. The surface is nitrided hardened + mirror-finish grinding， which makes it less likely to develop scratches or wear when in contact with high-pressure diesel for a long time， effectively reducing internal oil pressure leakage and ensuring stable and long-lasting fuel supply pressure.
The multi-specification precise flow-diverting oil holes layout ensures a linear and smooth oil pressure adjustment.
The valve body and valve plates have differentiated-sized flow-diverting oil holes， ensuring uniform fuel diversion and a gradual change in oil pressure， eliminating acceleration jolts， uneven power between high and low speeds， and reducing fuel atomization and carbon deposits and black smoke in the exhaust.
The high-precision solid sealing steel balls fit tightly and prevent leakage， eliminating the problem of fuel dripping into the cylinder during power failure and solving difficulties in cold start and accumulation of carbon deposits in the cylinder.
The micro-hole processing technology without burrs is smooth and free from processing burrs， making it less likely for the fuel injector to get stuck or clogged， reducing the frequency of stuck problems， and extending the service life of the entire set of components. Applicable scenarios
This product is suitable for heavy-duty freight trucks with electronic control common rail systems, large mining excavators, heavy-duty loaders, high-power fixed diesel generators, and is applicable to mining areas and construction sites for 24-hour full-load operation under high temperature and high dust conditions. It is suitable for the overhaul of heavy-duty diesel power injection systems in mining areas.
