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 and temperature data shown on the valve is in compliance
with the operating conditions of the piping. (
ð
Section 5, Page 15)
▪
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.
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.
CAUTION
Incorrect venting. Too many air pockets or gas pockets in the fluid handled
Flow rate measurement using ultrasonic equipment is limited or impossible!
▷ Properly vent the system before commissioning/start-up.
Functional testing prior to commissioning/start-up
Check the shut-off function of the installed valve by opening and closing it several
times.
7.1.2 Valve 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 shown on the top of the handwheel.
Depending on the flow rate to be set, balancing valves are opened or set to the
required valve plug position. Since the valves come with throttling plugs as standard,
they are suitable for both on/off and control duties.
