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, troubleshooting, 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
replacement 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 maintenance. 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).
Actuator Clearance Actuator Clearance
size (mm) size (mm)
37/47 95 P2 140
38/48 140 P3 140
39/49 140 P4 140
39D/49D 140 P5 140
1.2.4 After installing, check direction of flow again. The direction of flow is shown by the arrow on the housing.
1.3 QUICK CHECK:
Before operating, check the valve as follows:
1.3.1 Open and close the valve, and observe the movement of the actuator stem. The movement must be
smooth and linear.
1.3.2 Check for maximum stroke through change of signal (for pneumatic positioners, 0.2 - 1.0 bar or corresponding split-range values; for IP positioners, 420 or 0-20 mA).
1.3.3 Check all air connections for leaks.
1.3.4 The packing gland nut must always be tightened
slightly more than finger-tight.
IMPORTANT: An excessively tightened gland nut
can cause excessive packing wear and can hinder
the free movement of the plug stem.
1.3.5 Check fail-safe position. To do this, close supply pressure and observe whether the valve opens or closes
as prescribed.
1.3.6 After using at fluctuating temperatures, re-tighten all
bolt connections and check for leaks.
2 MAINTENANCE
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 leak free.
Check valves for correct functioning at regular
intervals (at least once every 6 months) as follows.
This check can be made when installed and in many
cases without interrupting production. If internal
defects are suspected, see section on „Disassembly
and Assembly of Valve“.
2.1 Examine gaskets for leaks and if necessary re-tighten
bolts (see Fig. 1).
2.2 Check bellows gasket and test connection - if present - for
external leaks.
2.3 Check valve for damage caused by corrosive residues
or corrosive vapours.
2.4 Clean valves and if necessary repaint.
2.5 Check packing bolts for correct tightening. Gland nuts
on packing may only be tightened slightly more than
finger-tight, or only tight enough to ensure a proper
seal.

IMPORTANT: An excessively tightened gland nut can
cause excessive packing wear and can hinder the
free movement of the plug stem.
2.6 If possible, open and close valve and check for maximum stroke and smooth movement of the plug stem.
Irregular movement of the plug stem may indicate
internal defects.
Note: With graphite packing, irregular movement of
the plug stem is normal.
IMPORTANT: Keep hands, hair, clothing, etc. away
from all moving parts. Failure to do so can lead to
serious injury.
2.7 Check all accessories for firm seating.
2.8 If possible, close supply pressure and check the failsafe position.

2.10 Check stem boot for wear.
2.11 Check actuator for leaks. To do this, spray housing,
air connections and plug stem guide with leak spray
and note any bubble formation.
2.12 Clean plug stem.
2.13 Check air filter, if present, and if necessary replace
insert.
