Maintenance 7 Maintenance The control valve is subject to natural wear. Depending on the conditions the valve is op- erated in, it needs to be checked at regular intervals. If leakage to the atmosphere occurs, remove the valve from the pipeline and replace the damaged parts. Warning! For maintenance work on the valve, make sure the relevant section of the pipeline is depressurized and, depending on the process medium, drained as well. For high medium temperatures, allow the section of the pipeli
