III.Functional Characteristics Analysis
1.Two-stage valve core design
Pilot stage:
Adopts nozzle baffle structure to convert electrical signal into hydraulic signal to achieve high-precision initial control.
Power stage:
Sliding valve structure,amplifies pilot stage signal,drives main valve core to move,and outputs large flow/high-pressure hydraulic oil.
Advantages:
Low power consumption(pilot stage only requires small current),high efficiency(power stage directly drives load).
2.Dynamic pressure compensation
Built-in pressure compensator:
Automatically adjusts valve port pressure drop to ensure that flow output is independent of load pressure and improve system stability.
Application scenarios:
Systems with frequent load changes(such as injection molding machine clamping cylinders)to avoid unstable flow caused by pressure fluctuations.
3.Fault diagnosis and protection
Self-diagnosis function:
Monitor input signals,feedback signals,valve core positions,and alarm through LED indicators or communication interfaces.
Protection mechanism:
Overpressure protection:When the oil supply pressure exceeds the set value,the valve port is automatically closed.
Overheat protection:When the valve body temperature exceeds 100℃,it triggers power reduction operation.
