Description
Product Overview
The fuel metering unit is installed at the low-pressure intake end of the high-pressure common rail oil pump, receiving electrical control signals to precisely regulate the fuel flow entering the pump, thereby dynamically stabilizing the working pressure of the fuel rail. Long-term wear from diesel impurities, aging coils, and valve core sticking can lead to out-of-control fuel supply, abnormal rail pressure, difficulty starting, and limited power. This integrated metering valve is factory-tested for flow and sealing performance. The entire machine can be replaced without disassembling the oil pump, suitable for heavy-duty trucks, large construction machinery, and agricultural common rail diesel equipment for major overhaul and replacement of the fuel supply system.
Unique core features of this unit
Double-flange metal fixed base, stable installation and resistant to vibration
Integrated stamping double-flange installation seat, reserved standard bolt holes, after locking, it fits the oil pump housing, the valve body will not shift or loosen under long-term vehicle vibration and heavy-load conditions, ensuring continuous and stable flow regulation accuracy.
Stainless steel integrated valve body, resistant to diesel corrosion and high-pressure deformation
Main body is precisely machined from stainless steel, with a surface passivation anti-rust treatment, able to withstand long-term exposure to diesel, oil pump internal oil pressure shock, and is less prone to rust and valve core sticking, with a longer service life compared to ordinary galvanized valve bodies.
Black side-mounted snap-in waterproof electronic control plug, stable signal transmission
Side-mounted integrated black plastic-sealed electronic control connector, with multiple layers of waterproof and dust-proof rubber rings inside, isolating the engine compartment oil, rainwater, and dust erosion. In bumpy conditions, the pins are less likely to oxidize and falsely connect, and the flow regulation signal is not delayed or lost.
Front transparent plastic dust-proof protective cap, protecting the precise valve core
Pre-installed transparent dust-proof plug at the oil outlet end, preventing sand and impurities from entering the valve core cavity during storage and transportation, avoiding valve core sticking and flow regulation failure after installation, reducing maintenance rework rate.
Built-in high-precision electromagnetic valve core, linear flow regulation without fluctuations
Internal precision electromagnetic control valve core, synchronous response to electrical control signals, linear and stable fuel flow regulation in high and low load ranges, eliminating acceleration jolts, imbalance at high and low speeds, and excessive black smoke from exhaust. Applicable scenarios
Suitable for heavy-duty freight trucks, large mining excavators, heavy-duty loaders, high-power stationary diesel generators, and heavy-duty diesel power supply systems for 24-hour continuous full-load, high-temperature, high-dust, and heavy-duty common rail diesel equipment in mining areas and construction sites.
