1.1 “As delivered” status
Valves are generally delivered as tested and assembled
units with the actuators fitted. Parts of the body and
actuator subject to corrosion are protected by a coat of paint.
Unpainted components are greased and the openings of the
housings are closed with plugs. High-grade steel housings are
delivered without a protective coat of paint (pickled or blasted).
1.1.1 Transport
Careful loading and transport arrangements are required to
avoid the product suffering impact and jolting movements. Do
not allow lifting gear to be attached to the valve spindle. We
recommend the use of a length of rope that is looped around
the valve head underneath the yoke (or the column opposite the
indicator scale). Promptly touch up any damage to the corrosion
protection.
1.1.2 Storage
Upon arrival on site, store the control valve on a solid base in a
closed room. Until its installation, the valve must be protected
from the weather, dirt and other potentially harmful influences.
Under no circumstances should the valve remain in storage for
more than 6 months. Do not remove the plugs protecting the
flanges and the inside of the control valve until it has arrived at
its place of installation.
1.2 Preparation for installation into the piping
The pressure, leak and operation tests performed in the
factory and the quality management system introduced by the
manufacturer ensure that the execution of the control valve
complies with the specifications set forth in the contract The
series number and the vital valve actuator data are found on the
rating plate.
Before installing the valve, carefully clean the piping.
Rating plate
As the information on rating plates reflects the special features
of the type they describe, their appearance may differ. The
rating plate contains the following data:
Typ / Type Fabrikations Nr. / Serial No.
DN / PN Mat. Gehäuse / Mat. Body
Kvs / Cv p
B B
Primärdruck / Inlet Pressure
max. Betriebstemperatur / Working Temperature p
B B
