4. Upon removing the control valve from the packaging,
we recommend that you:
• Promptly touch up any damage to the corrosion pro-
tection.
• Contact your shipper immediately to report any
damage.
• Call your Flowserve representative if you experience
any problems.
• Do not remove the protective covers from the body
flanges of the control valve or from the instrument
ports of the actuator and accessories until the valve
is ready for installation at the site.
Prior to installation of the actuator, we require, that you check the following conditions to reduce the risk of malfunction and
safety related incidents.
No.
Check
Possible malfunction or safety related incident
1
Confirm that the nominal / operational data on the
serial plate matches the operational data of the
facility.
An operational mismatch can cause considerable damage to
the valve or may lead to a failure at the facility.
2
Confirm that the line is clear of dirt, welding slag,
chips, scale or other foreign material.
The risk of control valve damage due to foreign particles will be
reduced if a suitable strainer is installed upstream of the valve.
(Suggested mesh size of 0.004 inch (0,1 mm)
3
Confirm the piping flanges are coaxial, parallel, and
correspond with the face-to-face dimension of the
valve.
Incompatible sizing may result in excessive tension, valve
malfunction or flange connection leakage.
4
Confirm the piping is routed correctly and the valve is
free of additional piping forces.
Incorrect routing may result in leakage and / or potential valve
failure.
5
Confirm that the control valve can be installed in an
upright position whenever possible.
Non-upright positioning may increase wear in the packing,
resulting in leakage and premature wear.
9 Installation
The control valve must be installed and com-
missioned by qualified staff - personnel who are
familiar with the installation, commissioning
and operation of this product and possess the
relevant qualifications in their field of activity.
