5.1 General information/Safety regulations
The consultant, construction company or operator are responsible for positioning
and installing the valves. Planning errors and installation errors may impair the
reliable function of the valves and pose a substantial safety hazard.
DANGER
Dead-end valve
High-pressure hazard!
Risk of burns!
▷
Protect the valve against unauthorised and/or unintentional opening.
WARNING
Exposed rotating parts
Risk of injury!
▷
Do not touch rotating parts.
▷
When the equipment is in operation, perform any work with utmost caution.
▷
Take suitable precautions, e.g. provide safety covers.
CAUTION
Improper installation
Damage to the valve!
▷
Protect the body and body bonnet/cover from any impacts.
5.2 Installation position and location
For gate valves installed in horizontal pipes a vertical stem position is recommended
(handwheel or actuator on top, see position (a) shown below). Installation with the
stem in an inclined or horizontal position, e.g. in vertical pipes (positions b, c, g, h) is
permitted. In this case, however, the actuator must be adequately supported at the
site. Avoid any installation positions with the actuator hanging downward (positions
d, e, f – risk of dirt ingress into the packing area via the back seat).
