1 GENERAL INFORMATION
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
1.1 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 Report transport damage to the carrier immediately.
1.1.3 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.
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.
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.

1.3 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, 4-20
or 0-20 mA).
1.3.3 Check all air connections for leaks.
1.3.4 The packing follower must always be tight to ensure
that the packing kit (guide bush with O-Rings) functions correctly.
1.3.5 Check the wiper ring for damage.
1.3.6 Check fail-safe position. To do this, close supply pressure and observe whether the valve opens or closes
as prescribed.

1.3.7 After use at fluctuating temperatures, re-tighten all
bolt connections and check for leaks.
2 MAINTENANCE
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 valve for damage caused by corrosive residues
or corrosive vapours.
2.3 Clean valves and if necessary repaint.
2.4 Check that the packing follower is tight.
