PNEUMATIC BUTTERFLY VALVE WARNINGS
The maximum service life of the valve is specied in EN ISO 16136. This has been veried at the factory using ageing tests specied
in the standard.
Correct installation and handling of the valve, as well as adherence to the maximum pressure and temperature conditions specied
in this manual are essential in order to preserve the service life of the valve.
The liquid to be conduted must be compatible with the valve materials. Consult chemical resistance charts published by Cepex or
consult the technical department.
The use of tools to open or close the manual valve control is not recommended.
Before carrying out any maintenance operations on the pipe or valve, ensure that the system has been depressurised by releasing
the pressure and emptying the pipes, following the specic safety regulations for each product.
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 o-rings and follow the maintenance instructions set out in this manual. The
grease must be compatible with the valve materials.
Rapid closure of valves should be avoided to eliminate the possibility of water hammer causing damage to the system.
When using the valve as the nal element of an installation, the risks of the liquid should be taken into account and the pressure and
temperature should be controlled, according to the safety standards for each product.
All connections should be made following the instructions referring to electrical supply as set out in this manual. Ensure that all
cables are properly connected.
If the box at the end of the run needs to be opened, when it is closed again, check that it is correctly positioned to avoid any contact
with water. Also check that connectors are correctly positioned.
At all times, avoid contact, even accidental, with the actuated valve’s moving parts during operation and/or before it has come to
a complete standstill
Ensure that the start-up mechanisms are blocked before beginning any electrical or pneumatic maintenance. The following steps
should be followed before any modications to the actuated valve are made:
1.- Disconnect the electrovalve from the mains supply.
2.- Block the pneumatic system’s start-up mechanisms.
3.- Make sure that no voltage is running through the circuits, including the auxiliary circuits and supplementary services.
All the above should be taken as indicative and not directly linked to safety procedures, as specic safety regulations may be in
place in some cases.
IMPORTANT: As a result of the complexity of the subject, the installation, usage and maintenance instructions found in this manual
are not designed to cover all imaginable service and maintenance scenarios. Should any further instructions be required or specic
problems encountered, please do not hesitate to contact the distributor or valve manufacturer.
We strongly recommend to x the valve with ange adaptor and loose ange in both sides of the valve to keep the technical
characteristics of the valve.
In case of xing only the valve with screws from one side, the maximum supported pressure will be reduced in some factor (f = 0,4).
Please ask to Cepex technical department for the specic conditions of installation and possible changes in the performance of the valve.

EXTREME PNEUMATIC BUTTERFLY VALVE LUG TYPE
1. DEFINITION
Buttery valve for isolating the ow in liquid handling systems.
Design based on Standard EN ISO 16136 in accordance with Directive 97/23/EC.
The valve is available with PVC-U, CPVC, PP-H, PVDF and ABS discs and EPDM and FPM sealing gaskets.The choice of material for the
body and gaskets 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.
The pneumatic actuator controls the positions of the valve (closed / open).
Lug-style valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using sets of
bolts and no nuts.
The valve is installed between anges using a separate set of bolts for each ange.
This setup permits either side of the piping system to be disconnected without disturbing the other side.

6. INSTALLATION AND COMMISSIONING
Before starting the installation process, check that all the parts needed for the valve assembly are there, 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 the correct solvent or
welding tools are used.
To install the valve, follow best installation practice recommendations provided on the Cepex website, paying specic attention to
thermal expansion and pipe alignment.
When lling the pipes with liquid, check that all the air has been 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 anges. 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 anges (Fig. 6) and the maximum tightening
torque. All screws must be used in the ange 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. 7) and table (T5.2), 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). Misalignment on
assembly could cause problems with the valve operation.
The threads of the screws and the inserts must be cleaned and lubricated in order to avoid seizing between the screw and the
insert.
The conditions of the installations and ambience could need modications in the installation standards.
An unnecessary over-torque will damage the ange.

6. OPERATION OF THE ACTUATOR
6.1 SPRING RETURN NORMALLY CLOSED VALVE (Fig.8)
The valve is closed without an air supply. When the actuator is supplied with
pressurized air, the valve opens. If the supply of the pressurized air is closed and
the air can escape, the valve will be closed because of the actuator’s internal
springs.
A 3/2 solenoid valve or 5/2 solenoid valve is required to carry out the action. In
the case a normally closed monostable solenoid valve is installed, the electrical
signal should be maintained during the time that the valve needs to be kept
open.
In the case of a spring return actuator, Cepex will normally serve the closed
valve as standard.
6.2 SPRING RETURN NORMALLY OPEN VALVE (Fig. 9)
The valve is opened without an air supply. When the actuator is supplied with
pressurized air, the valve closes. If the supply of the pressurized air is closed and
the air can escape, the valve will be opened because of the actuator’s internal
springs.
A 3/2 solenoid valve or 5/2 solenoid valve is required to carry out the action. In
the case a normally closed monostable solenoid valve is installed, the electrical
signal should be maintained during the time that the valve needs to be kept
closed.
6.3 DOUBLE ACTING VALVE (Fig.10)
The valve has no dened fail safe position. The valve is opened and closed by
applying air pressure to the corresponding control connections.
A 5/2 solenoid valve is required to carry out the action. In the case a normally
closed monostable solenoid valve is installed, the electrical signal should be
maintained during the time that the valve needs to be kept open (according to
the drawing).
6.4 LIMIT SWITCH BOX
To electrically conrm the position of the valve, a limit switch box can be
mounted to the actuator according to NAMUR specication.
IP67 Protection. Temperature range: -20ºC to 80ºC.
Limit switch boxes are available made from plastic and aluminium.
Electromechanical SPDT switches are used as standard.
See the specic manual and the electrical diagram inside the box.
6.5 SOLENOID VALVE
Dierent types of solenoid valve can be installed dened by:
- 3/2 (3 ways, 2 positions) and 5/2 (5 ways, 2 positions).
- Power supply: 230 V AC, 110 V AC, 24 V AC, 24 V DC, 12 V DC.
- Monostable / bistable.
See the specic manual for more options.
Optionally, the solenoid valve can be sold included with the actuator; it can
then be assembled in the factory attached to the actuator (NAMUR VDE/VDI
3845 standard).
6.6 RELIEF REGULATORS
Cepex strongly recommend relief regulators be installed so as to control the
actuator’s operating speed and prevent water hammer.
The silencer can be included within the relief regulator.

7. OPERATION AND MAINTENANCE INSTRUCTIONS
It is recommended that the condition of the sealing gasket be regularly checked, since it may show 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 regularly check that the ange xing nuts are
tightened correctly, as per the recommended torque values specied above (T5.1).
Periodic movement should be carried out to avoid the locking of the valve during long periods of time when it is in a closed
position. It is advisable that the liquid be passed through before the valve is manoevred.
7.1 REPLACING THE SEALING GASKET
If the sealing gasket needs to be replaced, proceed as follows:
• Ensure that the system is depressurised by releasing the pressure and emptying the pipes,
following
the specic safety regulations for each product. Also check the temperature of the liquid and
follow safety standards for temperature.
• Remove the valve from the installation.
• Remove the handle, screws (20), nuts (21) and throttle plate (17).
• Remove the ring (8). Take o 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. 11).
• Once the bearing is out, remove the shaft (6), turn it and re-insert it (Fig. 12) 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 ow.
• Remove the sealing gasket. Fit the new sealing gasket; it needs to be folded and positioned
so that
it lines up with the shaft, according to the gasket indicator tab (Fig. 13).
WARNING: Before installing the new gasket, check the condition of the O-rings (9 and 11).
8. MOUNT AND DISMANTLE THE ACTUATOR
If the actuator or the valve needs to be replaced, proceed as follows:
1. Move the buttery valve to the closed position.
2. Depressurise and drain the plant or the plant component.
3. Depressurise the control medium.
4. Remove the control medium line(s) from the actuator.
5. Remove the screws, the washers and the nuts (7, 8 and 9, Fig. 1).
6. Remove the assembly of the pneumatic actuator (4) with the mounting clamp (5) from the
bare
shaft valve (Fig. 14).
7. Remove the screws (6) in order to dismantle the actuator from the mounting clamp.
8. In case the actuator needs to be be replaced by a handle, also remove the coupling bush
(4 Fig.1).
In order to assemble a new actuator or a new valve, proceed in the opposite direction to the
description above.
