Valves of Vexve X series are practically maintenance-free.
The need for maintenance is significantly reduced by selecting the correct valve for the application and
ensuring error-free installation, commissioning and use.
Warning:
When the valve is connected to the pipeline, the temperature of the external surface may
be dangerously high. Protect yourself from burns.
We recommend regularly checking the following:
• Check that the valve's surface is not damaged and that there are no discernible leaks from the shaft
structure.
• Repair any damage carefully.
In the event that the valve is used rarely (ten times per year or fewer), we recommend checking the follow-
ing to ensure the long-term reliability of the valve:
• Check that there are no discernible leaks from the stem structure, check the condition of the handle
or control knop, and check that the measuring blocks are sealed.
