Description
Product Overview
The pressure regulating valve is installed on the common rail pipe or the outlet end of the high-pressure oil pump. The electronic control unit regulates the current of the electromagnetic valve to control the valve core opening to achieve dynamic pressure stabilization. Under long-term conditions of thousands of bar high-pressure fuel flushing, impurities from diesel wear, and alternating hot and cold conditions in the engine compartment, the valve core sealing surface will wear, and the magnetic coil suction force will weaken. This may result in low/high rail pressure, power output discontinuity, engine shutdown and pressure relief, multiple spark plug startups, and excessive black smoke in exhaust. This product has standardized specifications for threads, electronic control parameters, and pressure regulating stroke. The valve core seal surface and magnetic coil are replaced separately for repair of abnormal oil pressure faults. It is suitable for the maintenance of light commercial vehicles, small and medium-sized construction machinery, and high-pressure common rail diesel engines with heavy-duty applications.
Core Advantages of the Single Item
Integrated stainless steel valve body, resistant to high pressure, rust prevention, and corrosion resistance
The entire stainless steel is precisely machined and formed as a single piece, with multiple layers of oil channels integrated. It can withstand continuous ultra-high oil pressure impact and is not prone to rust in a diesel and water vapor environment. It provides long-term oil circuit sealing.
Standard hexagonal disassembly platform, uniform force during disassembly and assembly, and less likely to be damaged
The hexagonal limit structure is compatible with standard wrenches. During disassembly and assembly, it will not squeeze the internal precision valve core and coil, avoiding deformation of the valve body and thread slippage.
Multiple layers of threads at the front end + built-in sealing ring, no leakage under high pressure
The precision rolled outer thread is combined with an internal oil-resistant sealing gasket. Multiple layers of sealing prevent high-pressure fuel from leaking through assembly gaps, ensuring stable common rail working oil pressure.
Side-mounted waterproof electronic control plug, stable signal transmission and corrosion resistance
Black integrated sealed electronic control connector, equipped with a dustproof and waterproof rubber ring, isolating engine compartment oil and water vapor, eliminating short circuits and signal loss, and ensuring no delay in pressure regulating response.
Built-in precision pressure regulating valve core, linear and smooth oil pressure adjustment
The valve core is paired and ground, with the current change corresponding to precise opening degree. It can smoothly adjust rail pressure under high and low load conditions, eliminating acceleration jolts and speed drift.
Factory-installed overall pressure calibration, no need for secondary adjustment during assembly
Each pressure regulating valve is independently tested for the pressure regulating range, sealing performance, and electromagnetic response speed. The parameters are unified, and after assembly, it can directly match the original vehicle electronic control system, quickly restoring equipment power.
