DEFINITION
Butterfly valve for isolating or regulating the flow in liquid handling systems. The liquid can flow in both directions.
Design based on the EN ISO 16136 Standard in accordance with the 97/23/EC Directive.
The valve is available with PVC-U, CPVC and PP discs and EPDM and FPM sealing gaskets. The choice of material for the disc and gasket
depends on the type of liquid to be carried and on the working temperature of the liquid, in accordance with the chemical resistance tables
available on our website and the pressure/temperature chart in this Manual (G4.1).
2.
WARNINGS
•
Carefully read these instructions before handling the valve and observe their recommendations. Any damage caused by failure to
observe these instructions is not covered by the warranty.
•
All connection and handling tasks must be performed by qualified personnel.
•
The maximum service life of the valve is specified in EN ISO 16136. It is verified on the production plant by aging tests specified in the
standard.
•
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 service life of the valve.
•
The driven liquid must be compatible with the valve materials. Consult chemical resistance charts published by Cepex or consult the
technical department.
•
Using tools for opening or closing the manual valve control is not recommended. This process must be done manually.
•
Before carrying out any maintenance operations on the pipe or valve, ensure that the system is depressurised by releasing the pressu-
re and emptying the pipes, following the specific safety regulations of each product.
•
Turning the handle 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. Store the valve in the original packa-
ging, protected against humidity and direct sunlight.
•
Before installation, check that the valve is undamaged and that it contains all the parts required for installation.
•
After long periods of inactivity, check the grease on the gasket and follow the maintenance instructions set out in this manual. The
grease must be compatible with the valve materials.
•
It is important to avoid rapid closure of valves to eliminate the possibility of water hammer causing damage to the pipeline.
•
When using the valve as the final element of a installation, take into account the risks of the liquid and control the pressure and tem-
perature, according to the standards of safety of each product.

INSTALLATION AND COMMISSIONING
Before starting the installation process, check that you have all the parts needed for the valve assembly, and that the materials, connection
type and nominal pressure are suitable for the installation.
For solvent or welded connections, ensure also that the parts to be connected are of the same material and that you are using the correct
solvent or welding tools.
To install the valve, follow best installation practice recommendations provided on the Cepex website, paying particular attention to thermal
expansion and pipe alignment.
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.
Valve assembly using standard ISO-DIN, ANSI, JIS and BS/E flanges.
Flat gaskets are not needed in the socket couplings, as they are
incorporated in the valve itself
. Observe the tightening sequence of the screws on the flanges (Fig. 5) and the maximum tightening torque.
It is essential that all the screws are installed in order to ensure proper operation of the valve.
The PP/PE sockets for butt welding must be chamfered as indicated in the diagram (Fig. 6) and table (T6.2), to ensure correct opening and
closing of the disc.
Install the valve once the sockets are solvent-bonded and dry, to avoid problems with the adhesive (entry of the latter into the valve).
Flanges must be well centred on the valve (pay special attention to measurements DN100-DN125 and DN200). Assembly misalignment
could cause problems with the valve operation.

OPERATION AND MAINTENANCE INSTRUCTIONS
It is recommended that the condition of the sealing gasket is checked regularly, since it may display signs of mechanical wear due to
pressure, handling and contact with the liquid. The sealing gasket should be greased in the disc contact area (the grease must be compatible
with the materials of the gasket and the disc). It is also advisable to check regularly that the flange fixing nuts are tightened correctly, as per
the recommended torque values specified above (T6.1).
In long periods of inactivity, and in case that the installation allows it, maintain the valve slightly open.
The manual gearbox is maintenance-free and greased for life.
To operate the valve, unlock the handle (13) removing the pin (16) and pulling the lever (15) upwards, releasing its teeth from the throttle
plate (15) then turning the handle in the appropriate direction.
To lock the valve, re-insert the pin (16) and, optionally, secure with a padlock.
7.2 Assembling and Removing the Handle
To assemble the handle:
· Fit the handle on the shaft while holding the lever. Place it so that, with the valve closed, the handle indicator
shows 90º on the throttle plate (17).
· Fit the washer (14), screw (22) and cap (19).
To remove the handle:
· Remove the round cap (19) from the handle, the screw (22) and the washer (14).
· Press the lever (15) fully upwards so that its teeth are fully disengaged from the teeth on the throttle plate (17).
· Remove the handle from the shaft (6).

7.1 Replacing the Sealing Gasket
Should it be necessary to replace the sealing gasket, proceed as follows:
· Ensure that the system is depressurised by releasing the pressure and emptying the pipes, following the
specific safety regulations of each product. Also check the temperature of the liquid and follow safety stan-
dards of temperature.
· Remove the valve from the installation.
· Remove the handle as per 7.2, screws (20), nuts (21) and throttle plate (17).
· Remove the ring (8). Take off the cap (7) and remove the screw (12).
· Tap on the shaft (6) with a rubber mallet until the bearing (4) is exposed from the bottom (Fig. 7).
· Once the bearing is out, remove the shaft (6), turn it and re-insert it (Fig. 8) from the bottom.
· Tap again until the bearings (4 and 5) emerge from the top. Remove the shaft again.
· Remove the disc by pressing in the direction of the liquid.
· Remove the sealing gasket. Fit the new sealing gasket; it needs to be warped and placed so that it lines up
with the shaft, according to the indication tab of the gasket (Fig. 9).
WARNING: Before installing the new gasket, check the condition of the O-rings (9 and 11).

The disc does not fully open or close.
The sockets were not correctly bevelled.
Disassemble the valve and bevel the sockets as indicated
in table T6.2.
Foreign materials in the compartment (adhesive, etc.).
Disassemble the valve and check for obstructions in the
disc and gasket contact area.
Excessive opening or closing torque.

disc and the working temperature. Replace the gasket.
Excessive flange torque.
Tighten flanges as indicated in section 6.
Misalignment between sockets and valve.
Disassemble the valve and reassemble with concentric
alignment (observe the correct tightening sequence and
torque).
The valve is not fully watertight at
the sockets.
Misalignment between sockets and valve.
Disassemble the valve and reassemble with concentric
alignment (observe the correct tightening sequence and
torque).
Flange screws not tight enough.
Tighten flanges as indicated in section 6.
The valve is not completely
watertight at the sealing gasket .
Inadequate chemicals.
Temperature out of range.
Excess pressure.
Conduction of abrasive elements.
Check compliance with the specifications in this
document.
Damaged sealing gasket.
Replace the gasket.
Valve operating torque
Operating torque values at rated pressure (PN)
and 20 °C in as new direct from the factory condi-
tion. Installation (flange tightening) and operating
(pressure and temperature) conditions will affect
these values. If automation of operation is required,
please contact the manufacturer.
