6 Commissioning/Start-up/Shutdown
6.1 Commissioning/Start-up
6.1.1 Prerequisites for commissioning/start-up
Before commissioning/start-up of the valve, ensure that the following requirements
are met:
▪ The material, pressure data and temperature data of the valve are compatible
with the operating conditions of the piping. (
ð
Section 4, Page 13)
▪
The material's chemical resistance and stability under load have been checked.
Functional testing prior to commissioning/start-up
Check the shut-off function of the installed valve by opening and closing it several
times.
6.1.2 Operating the valve
CAUTION
Using tools to actuate the valve
Damage to the valve as a result of excessive forces!
▷ Only actuate handwheel-operated valves by hand.
Viewed from above, the valve is closed by turning the handwheel in clockwise
direction, and opened by turning the handwheel in anti-clockwise direction. The
relevant symbols are shown on the top of the handwheel.
The moving part of the scale at the handwheel indicates the number of full turns.
The fixed part of the scale indicates tenths of a full turn. The valve is fully open in
position 4.0 and fully closed in position 0.0.
Fig. 2: Position indicator at the handwheel
CAUTION
Excessively long idle periods
Damage to the valve!
▷ Check the function by opening and closing the valve at least once or twice a
year.
6.1.3 Taking measurements
The volume flow rate can be indicated by combining the valve with a differential
pressure gauge. As the valve is equipped with a fixed orifice plate, the current valve
position does not need to be entered. Changes in volume flow rate caused by the
handwheel being turned are displayed directly on the screen of the measuring
computer.
