Installation
5.3.1

Installing the regulator

Note
Before installing the regulator, tighten the
stopper(s) at the side of the valve body using
a suitable box wrench (see 'Tightening
torques' in the Annex).
The regulator can be installed into the down-
stream pressure pipe (return flow pipe) or
the upstream pressure pipe (flow pipe) of the
plant. See installation examples in Fig. 5-2.
1. Close the shut-off valves (1, 6) upstream
and downstream of the regulator while
the regulator is being installed.
Î Mounting the valve
2. Remove the protective caps from the
valve ports before installing the valve.
3. Lift the valve using suitable lifting equip-
ment to the site of installation. Observe
the flow direction through the valve. The
arrow on the valve indicates the direction
of flow.
4. Make sure that the correct flange gaskets
are used.
5. Bolt the pipe to the valve free of stress.

Î Mounting the actuator
6. Fasten the actuator on the valve by tight-
ening the coupling nut (11). Observe the
alignment of the control line connection.
Observe the specified tightening torques
(see 'Tightening torques' in Annex).
Î Mounting the control line
7. Mount the control line onto the valve and
actuator. Observe the specified tighten-
ing torques (see 'Tightening torques' in
Annex).
Î Mounting the electric actuator
Note
Read the mounting and operating instruc-
tions of actuators with fail-safe action (see
documents listed under 'Referenced docu-
mentation' in the 'Safety instructions and
measures' section).
8. Mount the electric actuator (1) on the
valve connection (2). Refer to the associ-
ated mounting and operating instructions
of the electric actuator. Observe the
specified tightening torques (see 'Tighten-
ing torques' in Annex).
9. Connect the power supply to the electric
actuator (1). Refer to the associated
mounting and operating instructions of
the electric actuator.
10. Slowly open the shut-off valves in the
pipeline after the valve has been in-
stalled.
