After these requirements are confirmed, the valve can be installed and connected in the piping.

1. Remove the protective flange covers and coating from
the control valve; clean the flange gasket surface.
Unsuitable cleaning agents can dam-
age and cause leakage in PTFE and
graphite gaskets. Consult a current chemical resis-
tance list before applying.
2. Whenever possible the valve should be installed so that
actuator is in an upright position. Vertical installation of
the actuator permits easier valve maintenance.
3. Install and connect the control valve to the pipeline. Locate
gaskets in the center of the body flanges and secure nuts and
bolts. Use the bolts indicated in the Table 2 for installing the
valve in the pipeline, and then tighten alternately according
to good practice. The user must in all cases confirm the
capacity of the bolts to ensure a sufficiently tight gasket seal
for the expected service.
4. Connect the power supply and instrument signal lines.
• Connect the air supply and instrument signal lines.
