These instructions are designed to support you when
unpacking, installing and performing maintenance
work on the valves. Users and maintenance personnel should carefully read these instructions before
installing, operating or performing maintenance
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 reconditioning, 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
1.1UNPACKING
1.1.1Each delivery includes a packing slip. When unpacking, check all delivered valves and accessories using this packing slip.
1.1.2Report transport damage to the carrier immediately.
1.1.3In case of discrepancies, contact your nearest dealer.
1.2 INSTALLATION
1.2.1Clean tubing prior to installing.
1.2.2If 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
1.2.3Make sure that sufficient overhead clearance above
the actuator is maintained, to allow for disassembly
of plug from the valve body (see following table).

39D/49D140P5140
1.2.4After installing, check direction of flow again.
1.2.5If the valve is to be welded into the line, make sure
that the valve is shielded from excessive heat.
1.2.6Connect 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.
6 bar (87 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.

1.3QUICK CHECK:
Before operating, check the valve as follows:
1.3.1Open and close the valve, and observe the movement
of the actuator stem. The movement must be smooth
and linear.
1.3.2Check for maximum stroke through change of signal
(for pneumatic positioners, 0.2 - 1.0 bar or corresponding split-range values; for IP positioners, 4-20
or 0-20 mA).
1.3.3Check all air connections for leaks.
1.3.4The packing follower must always be tight to ensure
that the packing kit (guide bush with O-Rings) functions correctly.
1.3.5Check the wiper ring for damage.
1.3.6Check fail-safe position. To do this, close supply pressure and observe whether the valve opens or closes
as prescribed.
Fig. 1
1.3.7After use at fluctuating temperatures, re-tighten all
bolt connections and check for leaks.
2MAINTENANCE
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“.
2.1Examine gaskets for leaks and if necessary re-tighten
bolts (see Fig. 1).
2.2Check valve for damage caused by corrosive residues
or corrosive vapours.
2.3Clean valves and if necessary repaint.
2.4Check that the packing follower is tight.

2.5If 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.
2.7Check all accessories for firm seating.
2.8If possible, close supply pressure and check the failsafe position.
2.9Check stem boot for wear.
2.10Check actuator for leaks. To do this, spray housing,
air connections and plug stem guide with leak spray
and note any bubble formation.
2.11Clean plug stem.
2.12Check air filter, if present, and if necessary replace
insert.
3.2Assemble valve
Attention: All worn or damaged parts must be re-
placed. Reusable parts must be clean. All consumable items such as seals, O-Rings and gaskets must
always be renewed.
3.2.1Carefully enter the plug into the bonnet.
3.2.2Replace body/bonnet gasket.
3.2.3Carefully place the bonnet/plug assembly vertically
onto the body ensuring the body/bonnet gasket is
correctly seated.
3.2.4Insert the guide bush with O-Rings into the bonnet
using an assembly bushing (see Fig. 2) and tighten
down the packing follower.
3.2.5Place the clamp around the body an tighten the wingnut.
3DISASSEMBLE AND ASSEMBLE VALVE
General Information
We recommend separating the actuator from the
valve before commencing repair work.
However, many maintenance and adjusting operations can be carried out with the valve installed.
Attention: Never turn plug or perform any service
on the valve while the plug is in the seat ring. Doing so may cause irreparable damage to the trim
set. To ensure against this, always hold the plug
out of the seat while working on the valve assembly.
3.1Disassemble valve
3.1.1Disconnect actuator from valve body
3.1.2Loosen and remove the clamp.
3.1.3Carefully remove the bonnet complete with plug and
packing kit..

3.1.4Carefully remove the plug from the bonnet.
3.1.5Unscrew the packing follower and extract the packing kit from the top of the bonnet. Check the wiper
ring and O-Rings for damage.
