Installation
6.1
General
ATTENTION To avoid leakage, deformation or rupture of the body, the piping should be laid out in such a way that no
thrust or bending forces act on the valve bodies when they are installed and operational. The pipeline must be coplanar and
aligned and tension-free for the valve
ATTENTION Sealing faces of the flanges must be cleaned and undamaged.
lf construction work is still in progress, non-mounted valves must be protected against dust, sand and building
material etc.(cover with suitable means).
Do not use valve handles and gear hand wheels as footholds!
Valves and pipes used for high (> 60 °C) temperatures must either be fitted with a protective insulation, or there
must be warning signs fitted showing that it is dangerous to touch these valves.
lf a valve is used as end-valve in a pipe, this valve should be protected against unauthorized or unintentional
opening to prevent personal injury or damage to property
.
For drinking water installation make sure to use approved material for lubricant, cleaning, painting, etc.
If a valve is used as end-of-line on a pipe, this valve should be protected against unauthorized or unintentional
opening to prevent personal injury or damage to property.
The preferred flow direction of operation is indicated by an arrow on the body. Anyway, the valve is designed to
work, to be waterproof and resist to the pressure in both directions.
6.2
Recommended distance upstream and downstream of the valve
6.2.1 Recommended minimum distance between the position of the valve and of the T-piece or elbow
Also valid for valve placed at pump discharge
