EEC CONFORMITY
A - Our valves comply with European regulations (EEC) within the limits of use described in paragraph
B.
The CE mark on the valve indicates conformity to the following regulations :
B - Use limits :
Usage pressure must be lower than 10 bar for all products.
In case of dangerous gas
(1)
valve diameter (line) must be below 100 mm.
For use outside these limits, please contact our technical service.
(1)
dangerous gas : group 1 gas, identified by a letter on the label and on the security card
of the product :
E (for detonating gas), O (for fuel), F+, F and R10 (inflammable), T+ and T (toxic).
For additional information, please see regulation 1272/2008 "Labeling of dangerous products".
SPARE PARTS AND ACCESSORIES
On the half-body, mark the identification number of the valve, then please see the general
documentation or contact us.
Our technical services recommend the use of food grade silicone grease to reassemble the seals.
Please consult us in the event of a malfunction.

VALVE IDENTIFICATION
DEFINOX butterfly valves have an identification number on the valve half bodies 3. You will need
this number to identify any spare parts you may request.
USUABLE SEALS
The following seal types can be mounted on your valve:
NEOPRENE, EPDM, SILICONE, FOOD GRADE VITON, ACID-RESISTANT VITON
The technical department is at your disposal to help you choose the seal types best suited to your
process. Ensure that the grease used is compatible with elastomere seals, particularly EPDM.
VALVE INSTALLATION
Your equipment should be stored in its original packaging with the disc 1in the open position to
prevent damage to the valve and to avoid marking the seal. Disassemble the actuator assembly disc
seal 124514 or the handle disc seal 1245678910 11 before welding the
half bodies 3on the process line. Pay attention to the linear centering and rotation of the half
bodies 3(risk of jamming and excessive operating torque). The half-bodies must be aligned precisely
and held in position during welding operations (possible use of a centering rod to replace the flap
axes 1). Never use the half bodies 3to secure poorly aligned pipes. Provide disassembly fittings or
the option to separate the pipes for later disassembly of the valve during maintenance operations
(replacing the seal).
ASSEMBLING MANUAL BUTTERFLY VALVES
Make sure the flap 1is positioned correctly on its seal 2before positioning the disc between the two
half-bodies 3. The gradual tightening of the lock 45is performed with the disc 1in the closed
position. Using a reference movement, make sure that the disc 1turns normally and that complete
closure does not cause an abnormal torque. To prevent an unintentional release, fit the screws
with 4 5to the threadlocker. The square male end of the disc rod 1receives the square female end
of the handle 6. Pay attention to the respective position of the parts during assembly (a groove on the
top of the disc rod 1indicates the direction of the disc inside the valve). To correctly position the
handle 6on the half-body 3, it is necessary to press in the bush 8using a hammer, otherwise the
disc 1will be pulled by the screw 9and will center poorly on the seal, with a subsequent risk of a
leak occurring.
ASSEMBLING AUTOMATIC BUTTERFLY VALVES
Assemble the disc 1, the seal 2and the half-bodies 3as per assembly for the manual valve,
however, do not fit the two tops screws. For assembly in normally closed position, make sure the
disc 1is in the closed position (a groove on the top of the disc rod 1marks the direction of the disc
inside the valve), position the pointer 12 on the disc 1as shown in the drawing. Assemble the
operator 14 so that the holes on the half-bodies 3face the feet tappings 13 . Supply the actuator
with air to ensure that the tap functions correctly. The actuator is supplied with dry, filtered air at a
minimum pressure de 4.5 bars. The air couplings fitted to the operator are suitable for the connection of
flexible tubing with a diameter of 4/6.
