Procedure for commissioning

Proceed as follows to put a manually operated valve into operation:

Slowly (!) turn the handwheel anti-clockwise and slightly against the end resistance. If the valve is equipped with a position indicator (red-green), the colour of the dot on the display will change from red to green as you open the valve.

To close the valve, turn the handwheel clockwise, slightly but firmly against its end resistance. If the valve is equipped with a position indicator (red-green), the colour of the dot on the display will change from green to red when the valve is closed.

Pneumatically operated valves can only be put into operation via a connected pneumatic controller.
