Danger
The valve is under pressure during operation.
When loosening flanged connections or sealing plugs, hot water, steam,
corrosive fluids or toxic gases may escape. This presents the risk of severe
burns and scalds to the whole body or severe cases or 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.
