1.1 “As delivered” status
Control 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.
Under no circumstances should lifting gear be attached to
the valve spindle, travel indicator and any peripheral units, if
applicable. We recommend the use of a length of rope that
is looped around the valve head underneath the yoke (or the
transportation eyelet(s)). The maximum permitted carrying
capacity must be observed. 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, as the impregnation in the stuffing box
packing evaporates and leaks may develop. 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. The travel indicator shows the position of the
closure member relative to the seat.
Before installing the valve, carefully clean the piping.
