4 Conventional use and mode of action
The leakage butterfly valve is a shut-off valve for fluids. It prevents the mixture of
two mediums. For control and/or cleaning of the leakage room, in the middle
flange two leakage seat valves are located.
By means of handle and switch combination the valve is opened respectively
closed by a 90°-rotation of the discs (17+21).
At the same time the leakage seat valves (12) are manually opened respectively
closed via compulsory control.
To open respectively close the leakage butterfly valve, slightly pull the hand
lever (3) to loosen it from the arrest and turn it 90°. After release, the lever en-
gages in the provided boring.
The handle is standard fitted with end position arrest.
Floating bearings (16) integrated decrease the torque needed for operation con-
siderably. Furthermore, butterfly valve equipped with floating bearings are supe-
rior concerning hygiene to other constructions in the area of shaft feedthrough.
The M&S-leakage butterfly valve LSV07 is available in a DIN-finish and Inch-
finish. The valves are fitted with seals of type SV04/Type98 respectively
SV04/Type95.
Both types of seals guarantee a maximum vacuum safety due to their special
shaping.

To achieve a spectrum of use as wide as possible, seals (18) are available in
five different food safe qualities of elastomer (VMQ, EPDM, FKM, NBR, HNBR).
5 Transport and storage
5.1 Scrutinize consignment
Check if order complies to consignment on reception of the butterfly
valves.
Investigate condition of the consignment and check if it is complete.
Damages in transit, which are externally visible and/or missing packing units, are to be
specified on the waybill of the forwarder immediately. The forwarder is to be claimed reli-
able for recourse in writing immediately and M&S Armaturen GmbH is to be informed
about the incident.
Damages in transit which are not perceptible immediately, should be reclaimed at the for-
warder within 6 days.
Damages reclaimed later are for the account of the consignee.
5.2 Transport
The packing units/leakage butterfly valves are only allowed to be
transported with appropriate hoisting devices and lifting accessories.
Please pay attention to the symbols placed on the package.
Transport valve carefully to avoid damages by acts of violence or im-
provident loading and unloading.

6 Disassembly/Assembly
• Disassembly/Assembly only in depressurized systems!
6.1 Disassembly [see illustration 2]
(a) Remove plastic plug (1+2).
(b) Pull the hand lever (3) and disconnect the hex socket head cap screw (4), which is
exposed then, by means of a hex wrench/Allen key of wrench size 4 (= width
across flats).
(c) Disconnect second hex socket head cap screw (5) on the rotary knob with an Allen
key of wrench size 4.
(d) Now the complete switch combination including handle and cross bushing can be
detached upwards.
(e) Disconnect cheese-head screw (6) with Allen key of wrench size 4 on the lower ro-
tary knob. Draw off the rotary knob of the flap.
(f) Disconnect hexagon nut (7), pull out the hexagon screw (8) and take out the cen-
trepiece (10) with middle flange (9).
6.1.1 Disassembly of the leakage seat valve
(g) Disconnect setscrews (11) on the face side of the middle flanges with an Allen key
wrench size 3.
(h) Pull out leakage seat valves (12).
6.1.2 Disassembly of flap seal
(i) Disconnect hex socket head cap screw (13) with an Allen key wrench size 4, pull
out the screws and pull asunder the flanges (14+15). Take out flap with seal and
floating bearing.
(j) After removing the two floating bearings (16), turn the flap (17+21) until a position
of a 90°-angle to the seal (18) is reached. First of all the seal is edged over the
axis of the flap below and then at the top. It is important to pay attention that the
bead in the axis boring is not spoiled. The lower square of the leakage valve flap
(17) has to be disconnected before exchange of the seal. For that purpose the
gudgeoned fixation on the outline of the flap axis has to be removed.

• On assembly it is absolutely necessary to pay attention to the in-
stallation of the floating bearings (16)!!
• On assembly of flap (17+21) and seal (18), pay attention not to
spoil the axis boring of the seal.
• The set screws (11) of the leakage seat valves have to be
screwed tightly.
• Pay attention to the position of the leakage seat valve. Observe
the turning direction of the handle.
• Damages on the seal are to be avoided.
• Counter flanges have to be aligning to each other and are to be
adjusted accordant to definite position.
• Assemble the butterfly valve in a way assuring to avoid damages
(for example by means of material-handling vehicles).
• Take care of the respective national subscriptions and assigna-
tions.
• Protect butterfly valves and connections from damage and de-
struction.
• The butterfly valve is to be implied in the potential equalization by
means of appropriate assembly.
6.3 Installation / Starting up
• Leakage butterfly valve are to be installed only by qualified per-
sonnel, with adequate functional training, experience and knowl-
edge regarding the tasks conferred to them.
• Pay attention that:
- the leakage butterfly valve is installed zero-potential
- no objects (screws, tools, etc.) are included in the tube system.
- the thermal expansion of a medium “cooped in” and pressure
hammers cannot affect the flap. Accordant non-return valves and
relief valves should be provided.
6.4 Valve with welding sockets
• In the welding process, shape distortion can result which may af-
fect the function of the leakage butterfly valve. For this reason,
only weld butterfly valve flanges assembled without seal and flap.
For this, pull tight all screws.
7 Maintenance / Attendance
• It is not allowed to make modifications on the leakage butterfly
valve.

• On non-observance of these operating instructions or in case of
constructional modifications of the leakage butterfly valves, the li-
ability of M&S Armaturen GmbH in any kind is not applicable.
• A different utilization or a use beyond it is considered as not con-
ventional or intended. M&S Armaturen GmbH is not liable for
