▷ The valve and its surrounding system must be depressurised prior to any
maintenance work and installation work.
▷ If the bellows are defective and fluid escapes, depressurise the valve.
▷ Ensure the valve is depressurised before removing any drain plugs, opening
plugs 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.
The operator ensures that maintenance, inspection and installation are performed by
authorised, qualified specialist personnel who are thoroughly familiar with the
manual.

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.

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
Before removing the valve from the piping, ensure that the pipe has been taken
out of service and released for repair/maintenance work.
