SKZ type is the functional feature of intelligent electric actuator

1. Input/output signal failure judgment function (fully open/fully closed/hold); CPU fault protection function
2. Valve jamming judgment and handling function; Instant anti reversal function
3. Motor overcurrent and overtemperature detection and protection function; Automatic adjustment of motor rotation direction function
4. Accurate positioning function; Midway (electrical) limit function
5. Local manual operation function; Automatic adaptation to forward/reverse operation mode function

Standard configuration and classification:
The adjustable SKZ series can be equipped with two intelligent controller series devices, HYTA/HYTB
For example, SKZ40/25/380+HYTA: indicates a force thrust of 4000N and a stroke of 25mm. HYTA type controller is selected for the adjustment type three-phase electric actuator
The switch type SKZ series can be equipped with HYKA/HYKB intelligent switch controller series devices
For example, SKZ40/25/220+HYKA: indicates a force thrust of 4000N and a stroke of 25mm, using a HYKA type controller switch type single-phase electric actuator.
