Description
Product Overview
0954000240 The pressure limiting valve is installed at the end of the high-pressure common rail oil manifold, serving as a safety pressure stabilizing component for the oil circuit. When the fuel pressure within the manifold exceeds the rated safety threshold, the internal valve core automatically opens to release pressure and return excess fuel, stabilizing the system oil pressure and protecting the high-pressure components such as the oil manifold and injectors from being damaged by high-pressure impacts. If the old valve core is stuck or the seal is aging, there may be oil pressure loss and restricted power. By replacing this product, the safety pressure stabilizing function of the oil circuit can be restored. It is suitable for maintenance and replacement of light trucks, construction machinery, and passenger vehicle common rail systems.
Unique Core Features of the Single Product
Bidirectional segmented external thread design, compatible with standard installation holes of the oil manifold
Both the upper and lower ends of the valve body are processed with standard external threads. One end is screwed into the common rail pipe, and the other end is connected to the return oil pipeline. The thread pitch is uniform and regular, ensuring high assembly fit and less prone to slippage and leakage under high-pressure conditions.
Hexagonal locking clamping platform in the middle section, no damage to the threads during disassembly and assembly
The integrated hexagonal positioning block in the valve body is used to clamp and tighten the hexagonal position with a wrench during maintenance, eliminating the need to clamp the end threads, thus avoiding thread wear and slippage. The single-person disassembly and assembly operation is convenient and labor-saving.
Built-in precision spring pressure relief valve core, precise and stable pressure stabilization threshold
The valve body is equipped with a custom anti-pressure spring and sealing valve core. The pressure relief pressure is uniformly calibrated at the factory, and when the oil pressure exceeds the threshold, it quickly opens to release pressure, automatically closes when the pressure drops, maintaining the safe working pressure of the pipeline throughout, and preventing damage to the oil circuit components due to overpressure.
Galvanized anti-rust integrated steel valve body, resistant to oil and corrosion
The entire steel is treated with galvanization and anti-rust treatment. It is not prone to rust and corrosion even when immersed in diesel or exposed to cabin moisture for a long time. The valve body does not deform or crack and can continuously withstand high-pressure impacts, resulting in a longer service life.
Independent black sealing gasket pad for matching, assembly completed in one step
The factory provides a non-oil-resistant circular sealing gasket. When the valve body is connected to the oil manifold, it fills the gap, providing double barriers against high-pressure fuel leakage. There is no need to add additional sealing consumables for maintenance, reducing assembly leakage rework. Applicable scenarios
Suitable for various diesel common rail power units, including light-duty freight pickups, box-type light goods vehicles, small excavators, agricultural diesel machinery, mobile power generators. It is applicable for urban commuting, high and low temperature conditions in fields and construction sites, as well as dusty and light-load working conditions with high-pressure oil circuit protection.
