CAUTION
Improper installation
Damage to the valve!
▷
Remove the caps prior to installation.
▷
Clean the mating flange faces.
▷
Protect the body and bonnet/cover from any impacts.
CAUTION
Outdoor installation
Damage due to corrosion!
▷
Protect the valve appropriately against moisture.
CAUTION
Painting of pipes
Impairment of the valve's function and loss of information!
▷
Protect stem and plastic components prior to applying paint.
▷
Protect printed name plates prior to applying paint.
CAUTION
Impermissible load
Damage to the actuating element!
▷
Do not use the valve as a foothold.
NOTE
For the valves to reach the documented Kv values, the flow direction must
correspond to the flow direction arrow.
NOTE
The mating flange faces must be clean and undamaged and the gaskets on the
mating flanges must be properly centred.
NOTE
Use an appropriate tool to evenly tighten the bolts crosswise, applying the
permissible torques.
5.2 Installation position and location
Valves marked with a flow direction arrow must be installed such that the flow
direction of the fluid corresponds to the direction shown by the arrow on the valve
body.
Gate valves
Any installation position can be chosen for gate valves. For gate valves installed in
horizontal pipes a vertical stem position is recommended (handwheel or actuator on
top). Installation with the stem in a horizontal or inclined position (e.g. in a vertical
pipe) is permitted; in this case, however, the actuator must be adequately supported.
Globe valves
Globe valves can be installed in any position unless specified otherwise. The best
installation position is with the stem pointing vertically upwards. Installation with the
stem in a horizontal or inclined position (e.g. in a vertical pipe) is permitted; in this
case, however, the actuator must be adequately supported.
