Description
Product Overview
The hydraulic pressure regulating valve is installed at the end of the high-pressure common rail pipe, receiving the vehicle's electronic control signals. It adjusts the fuel return opening by the expansion and contraction of the electromagnetic valve core to dynamically balance the working oil pressure of the common rail pipeline. Under long-term mining heavy-load conditions, continuous high-pressure impact of thousands of bar, impurities from diesel washing, and alternating cold and hot vibrations in the engine compartment, the valve core sealing surface will wear, the coil response will attenuate, and the sealing rubber ring will age and harden. This may result in loss of control of the rail pressure, power interruption, rapid pressure relief after engine shutdown, and difficulties in cold start. This product has standardized specifications for threads, valve core stroke, and electronic control signal parameters. Replacing the regulating valve alone can repair the failure of oil pressure regulation. It is suitable for large mining excavators, heavy-duty long-distance trucks, and small passenger vehicles with electric control common rail diesel engines for maintenance and repair.
Core Advantages of the Single Item
The overall zinc-coated alloy steel valve body is rust-resistant and resistant to diesel corrosion, and is not prone to deformation.
The valve body is treated with overall hot zinc plating for rust prevention, isolating the engine compartment from water vapor, diesel oil, and oil gas erosion. The cylinder body is thickened for a pressure-bearing structure, which can withstand high-pressure fuel impact without cracking or leakage under long-term conditions. It is suitable for high-temperature and bumpy working environments.
The central integrated hexagonal limit platform is evenly stressed during disassembly and assembly without damaging the valve core.
The middle section of the valve body has a complete hexagonal clamping structure, which is compatible with standard socket wrenches. During disassembly and assembly, the stress is evenly distributed, and the internal precision valve core will not be twisted or compressed, avoiding valve body deformation and thread slippage, and preventing damage to the sealing structure.
The front end has multiple layers of oil-resistant sealing gaskets, which prevent fuel leakage in high-pressure conditions.
The regulating valve core is surrounded by multiple layers of fluorine rubber sealing rings, which tightly fill the gap between the valve core and the valve body. In high-pressure fuel environments, there is no internal or external leakage, stabilizing the base oil pressure of the pipeline, and preventing abnormal pressure relief.
The side-mounted black waterproof electronic control plug is stable in signal transmission and resistant to electromagnetic interference.
The side-mounted integrated black insulating and sealing plug connector has a built-in dustproof and waterproof rubber gasket, isolating the engine compartment from oil stains and water vapor, eliminating short circuits and loss of oil pressure regulation signals. The valve core opening and closing response has no delay.
High-precision telescopic regulating valve core with small linear error in oil pressure regulation
The internal parts are paired with precisely ground valve cores and valve seats, which adjust the fuel return flow synchronously with the electronic control signals. From idle to heavy load, the rail pressure control is stable, eliminating vehicle speed drift and acceleration power discontinuity.
The entire oil pressure is calibrated before leaving the factory, and no secondary calibration is required during installation.
Each valve body is independently calibrated for current - oil pressure corresponding curves. The factory electronic control parameters are unified, and after assembly, it can directly match the original vehicle's electronic control system, quickly restoring stable oil supply and power output.
