WARNING
Valve under pressure
High-pressure hazard!
Leakage of hot and/or toxic fluids!
Risk of burns!
▷ The valve and its surrounding system must be depressurised prior to any
maintenance and installation work.
▷ If the bellows are defective or fluid escapes, ensure the valve is depressurised.
▷ Ensure the valve is depressurised before removing any drain, opening or vent
plugs.
▷ Allow the valve to cool down so that the temperature is below the fluid's
vaporisation temperature in all areas in contact with the fluid in order to
effectively prevent any risk of scalding.
▷ Never vent the valve by removing the bonnet/cover bolting or gland packing.
▷ Use appropriate spare parts and tools, even in emergencies.
Before removing the valve, ensure that the pipe has been shut off and released for
repair/maintenance work.
A regular maintenance schedule will help avoid expensive repairs and contribute to
trouble-free, reliable operation of the valve with a minimum of servicing/
maintenance expenditure and work.
The user is responsible for defining appropriate intervals for checks and
maintenance, depending on the application of the valve.
NOTE
All maintenance, service and installation work can be carried out by KSB Service or
authorised workshops. Find your contact on the Internet at

Never use force when removing and installing the valve.

7.2 Maintenance

The valve has been designed to be largely maintenance-free. The materials of the
sliding parts have been selected to ensure minimum wear. The stem seal is
maintenance-free and does not require re-tightening.
All elastomers are organic substances and as such subject to natural ageing.
Continuous operation at high operating temperatures may reduce their service lives.
The service life can be extended by taking the following measures:
▪ Checking the function by opening and closing the valve at least once or twice a
year
