Pressure Equipment Directive (PED)
Important Notes
Safety note
The valve must only be installed and commissioned by qualified staff.
Maintenance and service work must only be performed by adequately trained persons who have a
recognised level of competence.
The valve is under pressure during operation.
When loosening flanged connections or sealing plugs, hot water, steam, corrosive liquids
or toxic gases may escape. This presents the danger of severe burns and scalds to the
whole body or severe cases of poisoning.
Installation and maintenance work should only be carried out when the system is
depressurized.
The valve becomes hot or extremely cold during operation. This presents the risk of
severe burns to hands and arms. Installation and maintenance work should only be
carried out at room temperatures.
Sharp edges on internals present a danger of cuts to hands. Always wear industrial
gloves for installation and maintenance work.
