Industrial Valves
Labeling
The devices are labelled with a metal name-plate, which is usually attached to the valve or to another suitable part of the device
if necessary (e.g. extension, bracket). Conformity with the European Directive for Pressure Equipment is confirmed when the
name-plate has a CE symbol with the ID number of the notified body (see Fig. 11).
The following details can be taken from the plate: Manufacturer, device type (type), nominal diameter (DN or NPS), nominal
pressure (PN or CL), order number (P.O.), permissible pressure (PS), permissible temperature (TS), Maximum permissible
differential pressure on the shut-off element (P shutoff trim), year and month of manufacture (date), fluid group and (tag no.), if
available.
The preferred flow direction of flow is marked by a directional arrow integrated in the valve body or affixed to the valve body at
a suitable location.
Further information may be available on additional metal plates.
Service
It is recommended to check the device regularly for external leaks and other adverse effects or anything conspicuous.
The Gland Packing usually consists of form-pressed expandable rings. In the event of leaks, alternately tighten the nuts on the
gland until the leak stops. If necessary, add additional packing rings. Observe the maximum permissible torques (see
“Replacing the gland packing”) or Page 8 table 1, if only torque values are required.
Complete packing and repair sets for maintenance of the valves are available from LEUSCH or/and the authorised LEUSCH
representative.
To select the right spare part kit, note all informations from the name- plate and communicate this to LEUSCH.
