1 GENERAL INFORMATION
These instructions are designed to support
you when unpacking, installing and per-
forming maintenance work on the valves.
Users and maintenance personnel should
carefully read these instructions before
installing, operating or performing main-
tenance work. There is a separate set of
instructions for accessories (special seat/plug
fittings, diaphragm actuators, handwheels,
special seats, etc.).
These instructions do not contain any
information on Kämmer positioners. For this,
see corresponding instructions for the
installation, maintenance, trouble-shooting,
adjustment and operation of Kämmer
positioners.
To avoid damage or injury to personnel
or equipment, always heed all warnings
and instructions. Unprofessional re-
conditioning, the use of foreign replace-
ment parts or the performance of other
maintenance steps than those described
here, may cause a loss of efficiency or
lead to personnel injury or damage to
parts, and render the warranty void
1.1 UNPACKING
1.1.1
Each delivery includes a packing slip. When
unpacking, check all delivered valves and
accessories using this packing slip.
1.1.2
Larger valves can be lifted using slings on
the yoke rods or, if present, on the lugs
provided for this purpose. If slings are used,
attach them so that the outer tubing or
attaching parts are not damaged.
Important: If slings are used, be aware that
the centre of gravity of the valve may be
above the lifting point. In this case, secure
or support the valve against rotating, to
prevent damage or personnel injury.
1.1.3
Report transport damage to the carrier
immediately.
1.1.4
In case of discrepancies, contact your
nearest dealer.
1.2
INSTALLATION
1.2.1
Clean tubing prior to installing.
1.2.2
If possible, install the valve in an upright
position (actuator on top), to ease maint-
enance. An upright installation position is
important with low-temperature applications,
in order to keep the distance between the
packing material and the medium as large as
possible. The packing material then retains
the ambient temperature as much as possible.
Important: Do not insulate extension
bonnets that are provided for hot or cold
services
1.2.3
Make sure that sufficient overhead clearance
above the actuator is maintained, to allow for
disassembly of plug from the valve body (see
following table).
1.2.4
After installing, check direction of flow again.
The direction of flow is shown by the arrow on
the housing.
1.2.5
If the valve is to be welded into the line, make
sure that the valve is shielded from excessive
heat.
1.2.6
Connect supply pressure and signal lines.
Control valves can be supplied with a
positioner. The end connections for supply
pressure and signal are clearly marked.
Actuator and positioner are suitable for max.
4.2 bar (60 psi) supply pressure. If the supply
pressure exceeds the pressure specified on
the nameplate, a pressure reducing station is
required. If instrument air is not available,
install an oil separator/air filter in the air inlet
line. All connections must be free of leaks.
