  • Page 10: 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). 10 / 39 Version 0 • DocID104070923 Internet: www.gefa.com • E-Mail: gefa@gefa.com...
  • Page 11: Assembly And Commissioning

    For operating temperatures up to max. 160°C, actuators can be mounted directly. For higher tem- peratures, a mounting kit between actuator and valve should serve as thermal insulation. 11 / 39 Version 0 • DocID 104070923 Internet: www.gefa.com • E-Mail: gefa@gefa.com...
  • Page 12: Installation Conditions

    The flow direction and installation position of the ball valve can be freely selected. For ball valves with pressure relief bore, the flow direction is marked on the ball valve. 12 / 39 Version 0 • DocID104070923 Internet: www.gefa.com • E-Mail: gefa@gefa.com...
