Description
Product Overview
The integrated control valve is assembled within the electrically controlled injector's central electric drive cavity. The on-board electronic control unit outputs an electromagnetic signal to drive the internal valve core to perform rapid reciprocating movements, controlling the pressure relief and locking of the internal high-pressure oil circuit, and precisely controlling the ignition timing, single-shot fuel injection volume, and the closing timing of the injector. Under long-term conditions of thousands of bar of high-pressure fuel, impurities in diesel particles grinding, mining / long-distance high-temperature vibration working conditions, the bottom diverter valve disc oil holes wear, the internal valve core sealing surface develops scratches, and the gap between the valve body's layered mating becomes larger. This may result in fuel leakage, oil pressure control disorder, equipment showing single-cylinder operation imbalance, climbing power weakness, low-temperature start difficulties, and excessive black smoke emissions from exhaust. This product has all its external dimensions, stepped segmented sizes, and bottom oil hole layout standardized processing. After disassembling the injector, replacing the control valve assembly alone can repair the failure of the electronic control injection. It is suitable for large-scale mining excavators, heavy-duty wheeled loaders, long-distance heavy-duty freight trucks, and large-power fixed diesel generator sets for maintenance.
Core Advantages of Each Unit
The layered segmented heat-treated alloy steel is integrated as one piece. It is resistant to pressure, wear, and deformation.
The valve body is precisely combined and processed from multiple layers of heat-treated quenched alloy steel. The surface is treated with wear-resistant strengthening treatment, capable of enduring extremely high-pressure fuel impact, and not prone to layering cracking or internal oil leakage under alternating cold and hot conditions and continuous vibration. It maintains a micro-meter-level precise mating gap for a long time.
The bottom multi-oil hole diverter valve disc evenly distributes the high-pressure fuel flow.
The bottom integrates multi-sized precision flow-diverting valve discs to optimize the fuel flow path, divert the impact force of the high-pressure medium, and balance the fuel supply flow for each injection, eliminating engine idle jitter and power imbalance caused by uneven fuel injection volume in a single cylinder.
The multi-stage stepped limit cylinder body, with coaxial no-offset jamming assembly
The external multi-stage stepped limit platform structure precisely positions and limits the valve body when installed in the injector cavity, preventing radial shaking and tilting of the valve body, ensuring the internal valve core's full coaxial reciprocating motion, and avoiding single-sided wear causing valve core jamming and sealing failure.
The outer wall is engraved with multiple layers of identification codes, facilitating quick matching of models during storage and maintenance.
The cylinder body is segmented with numbers and QR code identification marks. It resists long-term exposure to diesel and repeated wiping without removing the code, enabling quick differentiation of specifications and models during inventory storage, on-site disassembly, and assembly, and preventing incorrect installation from causing oil pressure loss and abnormal injection faults.
The internal pre-installed paired mirror-grounded valve core has no delay in electromagnetic opening and closing response.
The valve body is pre-installed with a one-to-one paired mirror-grounded valve core. The lifting and lowering action under electromagnetic force is sensitive, with synchronous and non-delayed electrical control signals, precisely controlling fuel injection start and stop, allowing the engine to idle smoothly and accelerate with linear power without jolts.
Each control valve is independently tested for performance at the factory, and no manual grinding or oil pressure adjustment is required during assembly.
Each valve is independently tested for electromagnetic response speed, high-pressure holding time, and flow accuracy of diversion. The factory performance parameters are unified, directly matching the corresponding injector cavity, eliminating the need for manual grinding and oil pressure adjustment, significantly reducing the disassembly and maintenance time of the injector.
