Description
Product Overview
095400-0310 Pressure Limiting Valve is installed in the high-pressure fuel common rail pipe and is the core component for overloading protection of the oil passage. When the fuel pressure inside the fuel rail exceeds the safety set value, the internal precision valve core automatically opens to release the pressure, directing the excess fuel back to the low-pressure oil circuit to prevent damage to the fuel rail, injector, and oil pump due to overpressure. When the old valve experiences valve core jamming, aging of the seal, or failure of pressure relief, replacing this product can quickly restore the stable pressure protection function of the oil circuit, suitable for maintenance and replacement of light-duty diesel passenger cars, light trucks, small construction machinery, and agricultural diesel generator sets.
Unique Core Features of the Single Product
Different-length dual-segment external threads, suitable for standard installation positions of the fuel rail
The design of different-length threads at both ends of the valve body distinguishes the length of the threads. The thick and long thread end is screwed into the body of the common rail pipe, while the short and thin thread end is connected to the return oil circuit. The thread pitch is precisely uniform, and it is tightly screwed together, making it less likely to have oil leakage through the thread gap under high-pressure conditions.
Central integrated hexagonal clamping platform, no damage to thread teeth during disassembly and assembly
The hexagonal positioning block is centrally arranged. During maintenance and disassembly, only the hexagonal position needs to be clamped and force applied, completely avoiding the two ends of the threads, eliminating thread wear, slippage, and deformation. The single-person disassembly and assembly operation is more effortless, reducing the probability of rework and leakage.
Built-in precise calibration pressure relief valve core, stable pressure threshold
The internal is equipped with a custom anti-pressure spring and hard-sealed valve core. The pressure relief pressure is uniformly calibrated at the factory, and when the oil pressure exceeds the threshold, it quickly opens for pressure relief, automatically closes and locks when the pressure drops, providing stable control of the pipeline oil pressure throughout the process, protecting the entire high-pressure oil circuit components.
Overall galvanized alloy steel valve body, rust-proof, oil-resistant, and resistant to high-pressure impact
The valve body is treated with galvanization for rust prevention, and it is less likely to rust when exposed to diesel immersion or water vapor in the engine compartment for a long time. The valve body structure is firm, capable of withstanding high-frequency and high-pressure impact for a long time, and is less likely to crack or deform.
Complementary independent circular sealing rubber gasket, no additional consumables required for assembly
The factory provides a rubber sealing gasket resistant to oil and high temperature. The sealing pad is filled between the valve body and the fuel rail joint, providing double barriers against high-pressure fuel leakage. After maintenance and disassembly, it can be directly assembled as a complete set, eliminating the need for separate purchase of gaskets. Applicable scenarios
It is compatible with various small and medium-sized diesel common rail power equipment, including diesel pickups, box-type light trucks, small excavators, agricultural tractors, mobile diesel generators, etc. It is suitable for urban commuting, short-distance field work, and dusty, high-temperature and low-temperature alternating heavy-load conditions at construction sites.
