Remove any impurities from the piping, e.g. by flushing the pipe with the valve
in fully open position.
▷
If necessary, install a strainer.
6.1.1 Prerequisites for commissioning/start-up
DANGER
Surge pressure/water hammer potentially occurring at high temperatures
Danger to life caused by burns or scalds!
▷ Do not exceed the valve's maximum permissible pressure.
▷
Use valves made of nodular cast iron or steel.
▷ The operator shall provide general safety measures for the system.
Before commissioning/start-up of the valve ensure that the following requirements
are met:
▪ The valve has been connected to the piping at both ends.
▪ The shut-off function of the installed valve has been checked by opening and
closing it several times.
▪ The piping has been flushed.
▪ The material, pressure data and temperature data of the valve are compatible
with the operating conditions of the piping. (
ð Section 6.2, Page 18)
▪ The material's chemical resistance and stability under load have been checked.
6.1.2 Functional test
The following functions must be checked:
