Description
Product Overview
The control valve is assembled inside the common rail injector. The valve body rises and lowers under the drive of electronic signals, precisely regulating the amount of fuel intake and outflow, directly determining the injection timing, injection volume, and atomization effect. Under long-term mining heavy-duty, continuous high-pressure fuel flushing at over 1000 bar, the valve body sealing surface wears out, the needle rod guide gap expands, resulting in single-cylinder fuel supply imbalance, weak acceleration, idle wobble, oil circuit pressure relief after engine shutdown, and the need for multiple starts to start the engine. This product features uniform standardization of valve body clearance, needle rod stroke, and thread positioning dimensions. After maintenance and disassembly, the control valve can be replaced alone to repair abnormal fuel injection faults, suitable for large-scale mining excavators, heavy-duty long-distance trucks, and large-power diesel generator sets for common rail injector maintenance and repair.
Core Advantages of the Single Item
Segmented quench-hardened mirror surface valve body, with extremely low leakage of high-pressure sealing
Double-layer separate metal shell, micro-micron mirror surface fine grinding of the inner and outer walls, overall quench-hardening treatment, capable of withstanding extremely high oil pressure for long-term impact, closely adheres under high-pressure conditions, significantly reducing fuel internal leakage and pressure relief.
Double-encoded marking on the outer wall, quick matching of models during inventory and maintenance
Metal surface engraved 32F61-00062 and the matching identification code, the characters are resistant to diesel soaking and repeated wiping without falling off, facilitating quick identification of specifications for storage and on-site maintenance, avoiding incorrect installation and causing disorder in fuel injection timing.
I-shaped slender precision guide needle rod, no offset or jamming during reciprocating motion
The lower end of the long guide needle rod is strictly calibrated for coaxiality, smooth and without jamming during up and down movement, precisely controlling the fuel flow cross-section, stable fuel injection volume under high and low loads, eliminating acceleration jolts and idle jitter.
Standard external thread at the end of the needle rod, fixed the valve body assembly depth after tightening, no displacement under vehicle vibration conditions, long-term ensuring stable fuel injection parameters.
Multi-layer interlocking sealing structure, blocking fuel leakage
The precision fitting of the segmented assembly surfaces of the valve body, no extra gaps, blocking the high-pressure fuel from entering the electromagnetic cavity through the valve body gap, avoiding coil short circuit and burnout.
Independent test stand flow calibration at the factory, no secondary adjustment required for assembly
Each control valve is individually tested for opening and closing response, fuel supply flow, and high-pressure sealing performance, with unified factory parameters. After replacement, it can quickly restore the engine's stable power output, reducing maintenance time.
