1、 Model code disassembly

2、 Core performance parameters

1. pressure parameterThe maximum working pressure is 350 bar, and the peak pressure can reach 420 bar, which can withstand high-pressure working conditions of industrial equipment (such as large hydraulic presses and heavy construction machinery).

2. flow parametersRated flow rate of 125 L/min (under a pressure difference of 10 bar), wide flow regulation range, and stepless control of 0-100% flow rate can be achieved through electrical signals.

3. control accuracyHysteresis ≤ 1% (ensuring small deviation between instructions and actual actions), response time ≤ 50ms (fast response to control signals, reducing action delay), high position repetition accuracy, suitable for scenarios with high requirements for action synchronization.

4. environmental adaptabilityWorking temperature range -20 ℃~80 ℃, protection level IP65 (in some installation forms), suitable for use in multiple environments such as industrial workshops and outdoor construction machinery.

3、 Structural and functional characteristics

1. Two level control structureAdopting a two-stage control system of "pilot stage+main stage", the pilot stage is driven by a proportional solenoid to drive the small valve core, while the main stage controls the movement of the large valve core through pilot pressure, balancing control accuracy and high flow output to avoid the problem of insufficient accuracy in single-stage control.

2. Integrated Electronic Components (OBE)Equipped with signal amplification and diagnostic functions, there is no need to configure external amplifiers, simplifying system wiring; At the same time, it can monitor the current of the electromagnet and the position of the valve core in real time, and provide feedback on faults (such as overcurrent and wire breakage) through LED indicator lights for quick troubleshooting.

3. Pressure compensation function (F1)Equipped with a built-in pressure compensation valve, it can automatically counteract the impact of system pressure fluctuations on flow rate, ensuring stable flow during load changes (such as hydraulic presses pressing different hardness materials), thereby ensuring uniform movement speed of actuating components (such as oil cylinders).

4. High anti pollution designThe valve core and valve sleeve are precision ground and matched with anti pollution sealing material (D3V related configuration), which can withstand a certain degree of impurities in hydraulic oil, reduce valve jamming failures caused by oil pollution, and extend service life.

4、 Typical application scenarios

• Heavy engineering machineryFor example, the boom and boom oil cylinder control of excavators weighing over 20 tons, as well as the amplitude and telescopic mechanism drive of cranes, require a large flow rate to ensure the movement speed, while relying on high-precision control to achieve smooth operation (such as micro adjustment during lifting).

• Industrial hydraulic equipmentThe clamping and injection action control of large injection molding machines (requiring pressure compensation to ensure stable injection speed and improve plastic part accuracy), the rolling mill pressing device and continuous casting machine crystallizer vibration system in the metallurgical industry (capable of withstanding high pressure conditions and adapting to continuous production needs).

• Large hydraulic pressSliding block motion control for stamping and bending machines weighing over 1000 tons, achieving pressure velocity curve matching for different processes through precise flow adjustment, meeting the forming requirements of different materials.
