Cepex UP.89.SF1 Mode D'emploi

ENGLISH
1. DEFINITION
Diaphragm valve for regulating flow in liquid handling systems.
The valve is available with a PVC-U, CPVC or PP-H body and with EPDM or FPM membranes. The choice of materials will
depend on the type of liquid handled by the system and the operating temperature. See the chemical resistance chart
available at our website and the pressure/temperature diagram contained in this manual (G4.1) for further information.
The colour of the indicator at the end of the stem indicates the membrane material: blue = EPDM, green = FPM.
2. WARNINGS
• Carefully read these instructions before handling the valve and follow the recommendations. Damage caused by failure to read these
instructions is not covered by the warranty.
• Connections and handling operations must be carried out by qualified personnel.
• The maximum useful life of the valve is as specified in EN ISO 16138.
• Correct installation and handling of the valve, as well as adherence to the maximum pressure and temperature conditions specified in
this manual are essential for preserving the useful life of the valve.
• The liquid handled by the system must meet the chemical resistance requirements set out in the chart provided by Cepex in its tech-
nical catalogue.
• We do not recommend the use of tools on the handwheel when opening and closing the valve. Operate the handwheel manually,
using a cloth if necessary.
• Before carrying out any maintenance operations on the pipe or valve, ensure that the system is depressurised by releasing the pres-
sure and emptying the pipes.
• Turning the handwheel when the safety lock is in place could damage the valve.
• Avoid shocks during transport, since they may damage the body and mechanism of the valve. Keep the valve stored in the original
packaging, protected from damp and from direct exposure to sunlight.
• Before installation, check that the valve displays no signs of damage and that all parts required for installation are present.

Maximum valve operating torque at nominal pressure
for the various diaphragm materials.
The values quoted for the maximum operating torque required on
the handwheel to completely close the valve are approximate and
are determined to ensure that the valve is completely closed with
water at nominal pressure and at a temperature of 20 ºC.
Nut tightening torques for the various diaphragm ma-
terials (20-G 3.1).
The torque values are approximate and are determined with no
pressure in the valve. Due to wear on the diaphragm, nuts may
need to be retightened with a higher torque value.

6. INSTALLATION AND COMMISSIONING
MATERIAL Q
Before commencing the installation process, check that you have all the parts needed for the assembly of the valve and that the materials,
PPO+GF 1
the connection type and the nominal pressure rating are suitable for the installation. For solvent socket or weld connections, you will also
need to check that the materials to be connected are the same and that the solvent or welding tools are suitable.
EPDM/FPM 1
Test the correct operation of the valve's regulation system both before and after installation.
POM 1 To install the valve, follow the best installation practice recommendations provided on the Cepex website, paying particular attention to
the thermal dilation and alignment of pipes. The base of the valve's body has two threaded holes, allowing the valve to act as one of the
PP+GF 1
installation's fixed points.
The Cepex website also contains instructions for connecting the different types of valve connections: male solvent socket or 3-piece
PP 2
connector, thermofusion, butt welded, threaded with 3-piece connector and flanged connector.
PP+GF 1
When filling the pipes with liquid, check that all the air is purged from the system and that the initial pressure does not exceed the nominal
pressure of the valve or of the system element with the lowest nominal pressure rating.
POM 1
PP 1 7. OPERATION AND MAINTENANCE INSTRUCTIONS
PP+GF 1
We recommend checking the condition of the diaphragm on a regular basis, since it may display signs
ABS 1
of mechanical wear due to pressure, operation and contact with the liquid. With the valve closed, the
diaphragm may become loose and therefore need to be retightened to the torque value specified in table
PP 1
T4.3.
PP 4 We also recommend that you regularly check that the fixing nuts are tightened correctly, in accordance
with the recommended torque value specified in this manual (T4.4).
PC 1
The valve's degree of aperture can be set to a fixed position using the safety lock on the handwheel. To
activate it, simply pull the lock outwards until it fits into one of the set positions. If the safety lock does not
PVC-U/CPVC/PP 1
fit into any of the set positions, slightly rotate the wheel and pull the lock outwards again until the hole on
PVC-U/CPVC/PP 2
the lock is completely free. It is possible to use a padlock to secure the position.

8. REPLACING THE DIAPHRAGM
Stainless steel 2
Before starting the diaphragm replacement process, first release all the pressure from the pipes that
Stainless steel 4
connect to the valve. Then follow the steps set out below:
Stainless steel 4
1. Fully open the valve by rotating the handwheel anti-clockwise.
Stainless steel 4
2. Remove both of the valve's lower covers (5): press on the sides and pull, as shown in the diagram.
EPDM/FPM 2
3. Release the 4 fixing screws (20) and remove the nuts and washers (19).
4. Pull on the top part of the valve by the handwheel to remove it from the body. This part will
contain the fixing screws (18).
5. We recommend that your remove the threaded stem (1) and the diaphragm (2) together from the
upper body by rotating the handwheel clockwise.
Kv Cv
6. For D20 and D25 valves, you can remove the diaphragm by pulling on it carefully, ensuring that
it is removed in one piece.
155 10,85
7. For D32, 40, 50 and 63 valves, unscrew the diaphragm in an anti-clockwise direction, supporting
158 11,06 the stem until the diaphragm is fully removed.
8. For D20 and D25 valves, replace the diaphragm by pressing it into the shaft. Grease the button on
292 20,45
the diaphragm with a silicon based lubricant to facilitate assembly.
9. For D32, 40, 50 and 63, screw the new diaphragm in place.
454 31,76
10. Re-assemble the stem inside the upper body by screwing it anti-clockwise and ensuring the anti-
648 45,41
rotation wings and diaphragm are correctly positioned.
11. Assemble the body, replacing the four washers and tightening the four nuts using the torque
871 61
value specified in the relevant table.
12. Replace the lower covers by introducing them sideways.

CAUSE
The diaphragm is damaged in the threaded stem
seating area.
Solid particles are preventing the valve from closing
completely.
The valve is not completely closed.
The fixing screws have become loose or have not
been tightened using the appropriate tightening
torque.
The diaphragm has split due to fatigue.
