Description
Product Overview
The common rail pressure regulating valve is installed in the high-pressure fuel common rail pipe. It is controlled by an electrical signal to open and close the internal valve core, dynamically adjusting the return oil flow and stabilizing the oil rail pressure within the rated range. After long-term high-pressure fuel erosion, the valve core may wear, the sealing ring may age, and the coil may malfunction, which can cause the rail pressure to remain consistently high or low, leading to insufficient combustion and power loss. The new integrated pressure regulating valve does not require disassembly for maintenance. By simply replacing the entire unit, the common rail system can return to its standard working oil pressure, suitable for heavy trucks, small construction machinery, and agricultural diesel equipment common rail systems for major repairs.
Unique core features of the single product
Segmented hardened stainless steel valve body, resistant to high pressure and diesel corrosion
The entire stainless steel is precisely machined and formed in segments, with a surface passivation anti-rust treatment. It can withstand high-pressure impacts from the common rail for a long time, and is not prone to rust or deformation even when soaked in diesel. Compared to ordinary galvanized valve bodies, its service life is significantly improved.
Multi-ring annular sealing groove structure, multiple layers of sealing to prevent high-pressure leakage
The threaded section is reserved with multiple layers of sealing grooves, and is combined with an oil-resistant sealing ring to layer-separate the high-pressure fuel. After assembly, there is no pressure relief or leakage, and the oil rail set pressure is stably maintained, avoiding fluctuations in oil pressure that cause power jolts.
Front-end miniature precision pressure regulating pin, with sensitive and no lag pressure regulation response
The head has an ultra-fine hard alloy pin, which, in combination with the internal electromagnetic coil, precisely controls the opening degree of the return oil. After the electrical signal is issued, the pressure regulation is completed instantly. There is no significant fluctuation in rail pressure during idle and heavy-load switching, optimizing power output and fuel consumption performance.
Side-mounted integrated black waterproof plug connector, resistant to oil stains and vibration
The black plastic-sealed electrical control connector on the side. The internal multi-layer waterproof and dust-proof rubber pads isolate the engine compartment oil, water vapor, and dust erosion. The plug pin contact remains stable under long-term vehicle bumping operations, and there will be no signal loss or rail pressure失控 error reporting.
Standard hexagonal clamping platform in the middle section， protection for screw threads
The integrated hexagonal plane in the valve body is used for wrench clamping at the hexagonal position for disassembly and assembly， completely avoiding the two ends of the threads， eliminating thread slippage and tooth wear， and reducing the probability of assembly leakage and rework. Applicable scenarios
Suitable for light-duty diesel freight vehicles, small wheeled excavators, agricultural tractors, mobile diesel generators, and for high-pressure oil circuit maintenance of diesel equipment with common rail system in urban commuting, field construction, high and low temperatures, and multiple dust conditions with light loads.
