1. High-low pressure two-stage output, large oil quantity.
2. A plunger type is adopted for low voltage to improve effective pressure.
3. Double-circuit electromagnetic wired remote control can solve the problem of slow return of large -tonnage long- stroke oil cylinder.
4. Pressure overload protection device avoids overpressure and thus damage the device.
5. Double circuits adopt 3-bit 4-direction electromagnetic value which can keep forward and return back. It keeps two oil circuits pressurize simultaneously so that the oil cylinder will not return back.
