Selection and installation notes
- The actuator's actuating force and stroke must match the close-off pressure and stroke of the valve it is fitted to.
- The supply voltage and control signal (3-position, DC 0…10 V or on/off) must match the controller output.
- Refer to the datasheet for mounting position and ambient temperature limits.
