7.1 Commissioning/Start-up
7.1.1 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 is compatible with
the operating conditions of the piping.
▪ The material's chemical resistance and stability under load have been checked.
CAUTION
Welding beads, scale and other impurities in the piping
Damage to the valve!
▷ Remove any impurities from the piping.
▷ If necessary, install a strainer.
1. Thoroughly clean, flush and blow through all vessels, pipelines and connections
(especially of new installations).
2. Remove the valve's flange covers before installing it in the piping.
3. Check that the inside of the valve is free from any foreign objects. Remove any
foreign objects.
4. If required, install a strainer in the piping.
Functional testing prior to commissioning/start-up
Check the shut-off function of the installed valve by opening and closing it several
times.
Visual inspection after/during commissioning/start-up
Check bonnet/cover bolting 902/920 or 901 on BOA-H, BOA-R and BOA-S with joint
ring 411 for tightness after the valve has been subjected to load conditions or heated
up for the first time. If leakage occurs or bonnet/cover bolting 902/920 or 901 is
loose, evenly re-tighten it crosswise.
DANGER
Failure to re-tighten bonnet/cover bolting after first loading
Leakage of hot and/or toxic fluids!
▷ Re-tighten bonnet/cover bolting 902/920 or 901, particularly of valves operated
at temperatures exceeding 200°C.
7.1.2 Actuation
Viewed from above, the valve is closed by turning the handwheel in clockwise
direction, and opened by turning the handwheel in counter-clockwise direction.
Direction symbols are found on the top of the handwheel.
Globe valves are normally used in either "fully open" or "fully closed" position. For
control duties, valves should be fitted with throttling plugs, unless throttling plugs
are installed as standard.
