Measures for preparation
4.4 Preparation for installation
Proceed as follows:
Î
Flush the pipelines.
The plant operator is responsible for clean-
ing the pipelines in the plant.
Î
Check the valve to make sure it is clean.
Î
Check the valve for damage.
Î
Check to make sure that the type desig-
nation, valve size, material, pressure rat-
ing, and temperature range of the valve
match the plant conditions (size and
pressure rating of the pipeline, medium
temperature etc.).
Î
For steam applications, make sure that
the pipelines are dry. Moisture will dam-
age the inside of the valve.
Î
Check any mounted pressure gauges to
make sure they function.
Î
When the valve and actuator are al-
ready assembled, check the tightening
torques of the bolted joints
(

WA 0029). Components may loosen
during transport.
