Important Notes
Safety note
The valve must only be installed by qualified staff.
Qualified staff are those persons who - through adequate training in engineering, the use and
application of safety equipment in accordance with regulations concerning safety systems, and first aid
& accident prevention - have achieved a recognised level of competence appropriate to the installation
and commissioning of this device.
Danger
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.
Usage for the intended purpose
The swing flap non-return valves CB 1.../CB 2... ensure unidirectional flow in pipes by preventing a
backflow of liquids or gases.
Use this equipment only within the specified pressure and temperature ratings and check corrosion
resistance and chemical suitability for the application in question.
