8.1 Safety regulations
WARNING
Fluids handled, consumables and supplies which are hot and/or pose a health
hazard
Risk of injury!
▷ Observe all relevant laws.
▷ When draining the fluid take appropriate measures to protect persons and the
environment.
▷ Decontaminate valves used in fluids posing a health hazard.
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 from the piping, 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.
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 dismantling and reassembling the valve.
8.2 Maintenance
The valve has been designed to be largely maintenance-free. The materials of the
sliding parts have been selected to ensure minimum wear.
All elastomers are organic substances and as such subject to natural ageing.
Continuous operation at high operating temperatures may reduce their service lives.
NOTE
The user is responsible for defining appropriate intervals for checks and
maintenance, depending on the application of the valve.
