5.3.15 Forged, Globe and Check valves
(class 4500)
All forged valves have been designed according to the following
standards and specifications : ASME B16.34.
Forged valves mainly consist of body, bonnet and the closing
as well as the actuating unit (only globe valve).
Stem seal area : The gland packing of globe valve which seals
the stem is tightened by the studs and nuts on the gland flange.
The bonnet is equipped with an integral back seat, which seats
the valve when stem is in upmost position.
Flow seal area : The integral seal faces of the body of globe
and check valves are hard faced. The disc of globe valves is
connected to the stem by T-head joint. The disc of check valves
is spring loaded.
Bonnet seal area : The bonnet is threaded and seal welded
to the body.

6 Installation
6.1 General
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 (100) when they are installed and operational.
Only remove the covers from the connection
ends just before installation. The sealing faces
of the flanges must be clean and undamaged.
The gaskets at the connecting flanges must be
precisely entered. Use only joints and gaskets of
approved materials. All holes provided in the flanges
must be used for the flange connection.
When painting the pipes, do not apply paint to bolts
and stem (200). If construction work is still in progress,
the valves must be protected against dust, sand and
building material etc. (cover with suitable means).
Do not use valve hand-wheels as footholds!
Valves and pipes used for high (>50 0 C) or low (<0 0 C)
temperatures must either be fitted with a protective
insulation, or there must be warning signs installed
showing that it is dangerous to touch these valves.
If 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.
