GENERAL INFORMATION
Process line equipment in accordance with European
pressure equipment directive 97/23/CE paragraph 3.3.
The multiway valve is stamped with a SERVINOX self
adhesive and marked with the manufacture serial number.
This manual corresponds to the instructions for use of the
multiway valve.
OPERATION
Those valves are used to close one or several process lines
or to dispatch the liquid to one or several ways.
The valve is sealed with PTFE rings.
CAUTION FOR USE
The multiway valve must be used for clear liquid products
from group 2 (see article 9 of European directive no.
97/23/CE). The maximum working pressure is 6 bars and
the maximum working temperature is 80°C.
When use at high fluid temperature, high temperature can
be reached on the surface of the body: risk of severe
burning.
This type of valve cannot be used as regulating valve.

STORAGE CONDITIONS
The valve must be kept in a clean and dry storage under
non-corrosive atmospheric conditions.
INSTALLATION
A means of lifting must be used to handle large diameters
valves. Slinging by lever or automatic control is forbidden.
Textile slings around the valve body must be used.
Before mounting of the valve, the following points must be
checked:
•Parallelism of the ends.
•Correct alignment of piping.
•Quality of the span of the ends.
Valve spatial requirement must be established by
provisionally installing the valves on piping.
Multiway valve with butt weld ends
Weld ends must be dismounted in order to proceed with
their welding. For the correct operation of the valves,
following precautions must be followed when proceeding of
the disassembling and the reassembly of the ends:
•Identify the position of the end connections in order to
replace them as they were at delivery.
•Above all take care that the small pure PTFE blocks
(Ref.23 and 24) are exactly replaced where they were; so
that the thickness of fastener originally defined is
restored (this chock might not be identical on all the
ways).
•In any case dismantle the pure PTFE sealing rings (Ref.
7) that are mounted in the body openings (Ref. 1) and
that support the key (Ref. 2). If one of these rings gets
out of its place during dismounting of the valve; very
carefully replace it in its initial position.
To dismount the weld ends (Ref. 14), the 4 screws (Ref. 12)
must be first unscrewed. The ends can then be released
from the body (Ref. 1). The valve must be then put on the
side.
The ends must be now welded on the piping.
When installing the valve and in order to respect its correct
sealing, the following operations must be carried out before
mounting the body of the valve:
•Remove any foreign matter from pipes (filings, burr,
etc...).
•Make sure that gaskets (Ref. 9) and rings (Ref. 7) are in
the correct position.
•Carefully replace body (Ref. 1) of the valve between the
ends.
•Screw all 4 screws (Ref. 12) of each end.

For a heating multiway valve, the dimensions that figure in
the table of dimensions are not valid.
APPLICATION USE
Once the valves are mounted, they must undergo the same
tests than the piping. The tightness of both the body and the
ends must be checked. The manoeuvrability must also be
verified. A resistance might be observed during the first
utilisations.
After the first operating hours, the tightening (ends, hat)
must be checked in pressure and temperature.
For an automatic multiway valve, several points have to be
checked: specifications of driving compressed air and
command, pneumatic connection directions, as well as the
correct rotation of the valve (identified by a mark on the hat).
When the valves are equipped with electro-distributor or
position sensor, the nature of the electric tensions and the
classification of the distributors and indications have to be
checked.

MAINTENANCE
The maintenance of the valve needs to be done on a regular
basis. The inspection frequencies shall depend on the
conditions of use and shall be individually determined in
each case.
We can provide you with spare kits according to the spare
part list. We advise you to always keep some in stock in
case of emergency.
Dismantling of the valve
For an automatic valve, first of all air flows and electric wire
from the proximity switches must be disconnected. Then
actuator and its yoke must be disassembled by unscrewing
the yoke fixation screws (Ref. 11).
For manual valve equipped with a limit stop and proximity
switches, first of all electric wire from the proximity switches
must be disconnected and then the limit stop must be
disassembled by unscrewing the fixation screws (Ref. 11).
These instructions should be followed to dismantle the
valve:
•Identify the position of the valve on the pipe and the
position of the end connections (Ref. 14).
•Unscrew the screws (Ref. 12) of the end connections
(Ref. 14), and the plain end in case of three ways valve.
•Remove the body (Ref. 1) of the valve from the pipes.
•It is necessary to identify if there are PTFE sealing rings
(Ref. 23 et 24).
•Remove the screws (Ref. 11) and dismantle the cap (Ref.
3).
•Extract the plug (Ref. 2).
•Remove the upper packing ring (Ref. 5).
•Remove the lower and upper gaskets (Ref. 8.1 and 8.2).
•Take out the connection gaskets (Ref. 9) and the PTFE
sealing rings (Ref. 7).
•Remove the lower packing ring (Ref. 6).
•Replace the gaskets and the PTFE rings.
Assembling of the valve
These instructions should be followed to assemble the
valve:
•Place the lower packing ring (Ref. 6) at the bottom of the
body (Ref. 1). Be careful with the position of this ring.
•Place the lower and upper gaskets (Ref. 8.1 and 8.2) on
the plug.
•Introduce the plug (Ref. 2) into the body (Ref. 1).
•Place the upper packing ring (Ref. 5). Be careful with the
position of this ring.
•Place the cap (Ref. 3) and tighten the screws (Ref. 11).
•Introduce the PTFE sealing rings (Ref. 7).
•Replace the connection gaskets (Ref. 9).
•Place the valve in a right position by introducing the ends
connections (Ref. 14) into the body (Ref. 1).
•Tighten the screws (Ref. 12).

To dismantle the actuator and its yoke, screws (Ref. 6) must
be first unscrewed. Then the unit must be vertically released
in order to set the driver (Rep. 3) free.
The actuation part of the valve is dismantled.
Actuation of the valve with hat-yoke
To dismantle the actuator and its yoke, screws (Ref. 11)
must be first unscrewed. Then the unit must be vertically
released in order to set the driver (Rep. 10) free. And finally
the screws (Ref. 31) must be unscrewed.
The actuation part of the valve is dismantled.
