All forged valves have been designed according to the
following standards and specifications: ASME B16.34, API
602.
Forged valves mainly consist of body, bonnet and the closing
as well as the actuating unit (only gate and globe valves).
Stem seal area: The gland packing of gate and globe valves
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 hard faced seat rings of gate valves and
swing check valves are swagged into the body. The solid
wedge of gate valves is connected to the stem by a “T” joint.
The integral seal faces of the body of globe and piston check
valves are hard faced. The turning disc of globe valves is
connected to the stem by a “T” joint. The disc of piston check
valves is spring loaded.
Bonnet seal area: The bonnet/yoke of class 800 valves is
bolted to the body. In some cases the bonnet or cover is seal
welded to the body upon the request of customer/order.

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
℃
) or low
(<0
℃
) 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.
