As the manufacturer of Hawido control valves, we undertake the inspections and revisions of all common pressure reducing valves.
In order to guarantee a trouble-free operation for years to come, the valves must be regularly serviced. These measures to preserve the quality of the valve ensure its trouble-free operation and consequently, the reliable supply of drinking water for your customers. Functional checks should be carried out once a year, including cleaning the filter screens in the dirt trap and the fine filter in the control line. The Hawido regulating valves is due for an inspection every four to six years. In this process, the main valve and the regulating valve are completely opened and all the small parts – diaphragm as well as the seals – are replaced. The inside of the valve must be visually inspected and cleaned. Once it has been commissioned again, the valve will again continue to perform its tasks for years.
Due to the service fee, the costs remain the same every year.
