Mounting and start-up
3. Lift the valve to the site of installation (see
section 4.2). Observe the flow direction
through the valve. The arrow on the
valve indicates the direction of flow.
4. Version with flanges: make sure that the
correct flange gaskets are used.
5. Version with threaded ends (female/
male thread) and flanges: bolt the valve
to the pipeline free of stress.
Version with welding ends: weld the
valve free of stress into the pipeline.
6. Depending on the field of application,
allow the valve to cool down to reach
ambient temperature before start up.
7. Slowly open the shut-off valve in the
pipeline after the valve has been in-
stalled.
Risk of valve damage due to a sudden pres-
sure increase and resulting high flow veloci-
ties.
Slowly open the shut-off valve in the pipeline
during start-up.
8. Check the valve to ensure it functions
properly and that there is no leakage.
