The flange type of a flanged model is given on the identifi-
cation plate.

Servicing is facilitated if the valve needs no support. If neces-
sary, you can support the valve by the body, using regular
pipe clamps and supports. Do not fasten supports to the
flange bolting or the actuator (see Fig. 9).

3.2.1

Valve insulation

If necessary, the valve may be insulated. Insulation must not
continue above the upper level of the valve body (see Fig.
10, 11, 12).       

3.3

Actuator

The plug position is indicated as follows:

by a marking on the positioner and

by a groove at the end of the valve stem and mark-
ings on side of the stem.

These are aligned with the plug. If there is any uncertainty
about the marking on the positioner, check the plug posi-
tion by the groove at the end of the stem or by markings on
side of the stem.

If possible, install the valve so that the actuator can be discon-
nected without removing the valve from the piping.

The actuator must not touch the pipeline, because pipeline
vibration may damage it or interfere with its operation.

In some cases, for instance when the actuator is exception-
ally large or when there is lot of piping vibration, it may be
advisable to support the actuator. Contact Metso’s Flow
Control for more instructions.

3.4

Commissioning

Ensure that no dirt or foreign objects are left inside the
valve or pipeline. Flush the pipeline carefully. Keep the
valve entirely open during flushing.

Check all joints, pipings and cables.

Check that the actuator, positioner and limit switches are
correctly adjusted. To adjust the devices, refer to their
installation, operation and service manuals.

NOTE:

When installing the actuator, make sure that the valve-
actuator combination functions properly. Detailed infor-
mation on actuator installation is given in Section 6 or in
separate actuator instructions.
