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.
