2 TRANSPORTATION, RECEPTION AND
STORAGE
Check the valve and the accompanying devices for any
damage that may have occurred during transport.
Store the valve carefully before installation, preferably
indoors in a dry place.
Do not take the valve to the intended location and do not
remove the flow port protectors until the valve is installed.
The valve is delivered in the closed position. A valve
equipped with a spring-return actuator is delivered in the
position determined by the spring.
3 INSTALLATION AND COMMISSIONING
3.1 General
Remove the flow port protectors and check that the valve is
clean inside.
3.2 Installing in the pipeline
Flush or blow the pipeline carefully before installing the
valve. Foreign particles, such as sand or pieces of welding
electrode, will damage the segment sealing surface and
seats.
The valve has an arrow indicating the flow direction. Install
the valve in the pipeline so that the flow direction of the
pipe corresponds to that marked on the valve. The mount-
ing position does not place restrictions on operation of the
valve, actuator or positioner. You should, however, avoid
installing the valve so that the shaft points downwards
because impurities travelling in the pipeline may then enter
the body cavity and damage the gland packing. See Fig. 14.
The RA and RE1 valves should be applicable to the pipe
flanges, see the table in 11.19.
Choose flange gaskets according to the operating condi-
tions.
Do not attempt to correct pipeline misalignment by means
of flange bolting.
Stress caused in the valve by pipeline vibration can be
reduced by supporting the pipeline properly. Reduced
vibration also helps ensure correct functioning of the posi-
tioner.
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. 15.
3.3 Actuator
The valve closed and open positions are indicated by a
groove at the end of the valve shaft. The groove shows the
position of the segment with respect to the flow port, see
Fig. 16.
If possible, install the valve so that the actuator can be discon-
nected without removing the valve from the piping.

CAUTION:
When handling the valve or the valve package, take its
weight into account!

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.
