First of all, the plug we use in our hydraulic solenoid valves could replace the weak coils, and all of the spools and bodies are interchangeable by retaining the same tolerance of internal leakage. Besides, all of the movable parts of the wet type coil solenoid valve are immersed in the oil, since those being with cushioning low noise.

The following sentences are features of our hydraulic solenoid valve: 

• High voltage test up to 1500 V/min.
• Insulation resistance test exceeds 100MΩ.
• Momentary signal shifting approx. 0.1sec.
• Spool shifting approx. 30,000,000 times.
• H class insulation coils which can resisted up to 180℃
