  • Page 17: Transport And Storage

    For valves that are delivered without actuation, the shut-off element is not secured against adjustment. It must be transported in such a way that it can not be opened from the closed position by external influences (eg vibration). 17 / 61 Version 10 • DocID 73998091 Internet: www.gefa.com • E-Mail: gefa@gefa.com...
  • Page 18: Mounting And Initial Operation

    If the exact end position is exceeded, bring the valve back into the open or partly open posi- tion. Then approach the end position again from the open position. 18 / 61 Version 10 • DocID 73998091 Internet: www.gefa.com • E-Mail: gefa@gefa.com...
