ATTENTION!
. . . Warning of general danger
2.2 Explanatory notes on safety information
In this Manual dangers, risks and items of safety information are highlighted to attract special attention.
Information marked with the symbol above describes practices, which if fail to comply with, can result in serious injury or
danger of death for users or third parties or in material damage to the system or the environment. It is vital to comply with
these practices and to monitor compliance.
All other information not specifi cally emphasized, as well as technical data in Data Sheets and product marking, must
also be observed and complied with to the fullest extent in order to avoid faults which in turn can cause serious injury to
persons or damage to property.
3. – PRESERVATION, STORAGE AND TRANSPORT
ATTENTION!
- Use proper packing for transportation.
- Keep storage protection before installation.
- The valve surface is protected by an epoxy paint. In order to prevent damage, corrosion or rust on the surface, avoid extreme temperatures (keep at 5ºC to 50ºC), avoid high environmental humidity or corrosive environment. Keep the valves
away from direct sunlight, dust, fl ames or rain. Protect rubbers also against UV light. Do not pile up excessive weight. In
case of severe bumping inspect the material for any damage and replace if necessary.
4. – DESCRIPTION
4.1 General Description / Operating principles
Self-acting Diaphragm Valves consist of a main valve and a pilot system commanding the action of the main valve
through the controlled variable, using the own energy of the fl uid. The valve operates without any input of signal or energy
from external sources, with exception of Solenoids to open/close function.
The main valve basically includes the body, the cover and the rubber diaphragm especially designed and reinforced,
that divides the inner cavity of the valve into fl uid fl owing area under the diaphragm and activation chamber above the
diaphragm. The Pilot circuit commands the closing and partial or total opening of the diaphragm by fi lling or emptying the
activation chamber with the same fl uid fl owing through the valve. The system reaches the equilibrium when the degree
of diaphragm opening is the one needed to keep the controlled variable at the preset value.
The soft sealing provided by the rubber diaphragm offers an optimum seat tightness.
Valve diagram with parts can be seen at the last page of the Manual.
- Protect against external force (impacts, vibrations, etc.)
- Product parts such as pilot circuit must not be used to take up external forces that they are not designed for:
e.g. do not use them as climbing aids, or as connecting points for lifting gear, etc.
- Allow only skilled personnel; suitable handling and lifting equipment must be used. See data sheet for
weights or consult manufacturer.
- Check correct position of nameplate and handle with care to avoid personnel cuttings.
- When the valve is operated, there is a crushing hazard between the diaphragm and the body. Ensure the
valve is not under operation in case hands are introduced inside the valve.

4.2 Area of Application
These valves represent a simple, economical, reliable and easy to maintain on-line solution for hydraulic applications for
open/close by Solenoid, as well as for control of pressure, fl ow, level, or combination thereof. Thus they are an excellent
choice for applications with irrigation or industrial water, where it is not normally required a high response speed, high
accuracy or low hysteresis, provided the fl uid and pressure and temperature conditions be compatible with the valve
building materials.

5. – INSTALLATION
5.1 General remarks on installation
The following points should be taken into account in addition to the general principles governing installation work:
ATTENTION!
- Remove fl ange covers or any other remaining packing/storage protection if present.
- The interior of the valve and the pipeline must be free of foreign particles.
- The valve is unidirectional. Follow the arrow in the cover for installation.
- Lay pipelines such that damaging transverse, bending and torsional forces are avoided.
- Protect valves from dirt during construction work.
- Protect the valve soft parts from heating caused by welding works at the plant during commissioning.
- Product parts such as pilot circuit must not be used to take up external forces that they are not designed for: e.g.
do not use them as climbing aids, or as connecting points for lifting gear, etc.
- Suitable materials handling and lifting equipment should be used for assembly work. During assembly work, ensure that the valve is fi xed adequately. See data sheet for weights.
-The preferred installation position is in horizontal pipeline with cover upwards, or alternatively in vertical pipelines.
- You must only operate the unmounted valve while observing all the safety measures.

5.2 Assembling additional modules
Optional accessories (limit switches, extensions, etc.) that are supplied with valves must be fi tted as required for their
functions as shown in the system plan.
Pilots and accessories: The valves are delivered fully assembled with Pilot, Solenoids, Manual Valve, tubing and accessories. Pilot drainage shall be led to a drainage pit or straight to atmosphere. In case of any counterpressure in this pipe,
it should never exceed the adjusted downstream pressure.
Working modes:
-Working mode 1: 4-Way Manual Valve in position “CLOSE (C)”
Main Valve is closed.
-Working mode 2: 4-Way Manual Valve in position “AUTO (A)”
2.1 With Solenoid 24VDC ON (energized, continuous voltage 24Vdc applied)
Main Valve working as Pressure Reducing Valve, operation controlled
by Pressure Reducing Pilot (PRP).
2.2 With Solenoid 24VDC OFF (de-energized, no voltage applied)
Main Valve is closed.
-Working mode 3: 4-Way Manual Valve in position “OPEN (O)”
3.1 With Solenoid latch “ON” (pulse voltage 9-30Vdc, ‘+’ to red cable, ‘-‘ to black cable)
Main Valve working as Pressure Reducing Valve, operation controlled
by Pressure Reducing Pilot (PRP).
3.2 With Solenoid latch “OFF” (pulse voltage 9-30Vdc, ‘+’ to black cable, ‘-‘ to red cable)
Main Valve is closed.
Page 4
ATTENTION!
- You must only operate the unmounted valve while observing all the safety measures.
- Avoid mechanical damage to the seat during handling, storage and installation.
- Check correct position of nameplate and handle with care to avoid personnel cuttings.
-When the valve is operated, there is a crushing hazard between the diaphragm and the body. Ensure the valve is
not under operation in case hands are introduced inside the valve.
- When the valve discharges to atmosphere, we recommend to set an orifi ce plate downstream of the valve properly
sized to control the fl ow rate and minimize cavitation. This will also help to diaphragm opening and will ease foreign
particles removal.
- When using the valve as an end seal, the employers’ liability insurance association of the gas and waterworks
specifi es the use of a safety precaution such as a plug-in disc, blind fl ange, tec. (observe the information in EN
13857). With a medium jet that freely exists, you must secure the exit area.
Before starting maintenance work on an end valve with a free stem end, you must mount a blind fl ange.
FOR FLANGED VALVES:
- Make sure that counter-fl anges are compatible with the standard of the valve fl anges. When matching up fl anges,
avoid gradients, rotation and pipe misalignment that could cause pipe and valve stress and leakage once installed.
Flanges should fi t smoothly. Select the proper fl ange face gaskets according to duty and centre them on the fl ange
face properly. Do not force the counter-fl anges and do not try to tighten the bolts when a gap exists between valve
and pipe or if misalignment is observed. Tighten in a crosswise, moderate and uniform manner. During start-up
tighten again if leakage is noticed or replace gasket if necessary.
FOR SCREWED END VALVES:
- Make sure that the pipe screw has the correct fi nish and compatible cone for the valve.
- Use proper sealant according to duty, such as hemp core, Tefl on, etc.
- Check that pipe introduction in the valve does not exceed its thread, leave a safety margin of minimum 1 mm.
- Tighten with a plain or adjustable wrench on the hexagon end of the valve only . Apply force to other area of valve
may seriously damage the valve. Do not use hook spanners or other wrenches that could damage the hexagon
surface. Valve should be threaded smoothly. If not, do not try to force the thread and avoid wrench extensions
since this could lead to breaking the valve or damaging the thread. A general recommendation is not to exceed the
tightening torque of 30Nm.

ON/OFF ON Main valve controlled by PRP
Main Valve working as Pressure Reducing Valve:
The valve is working to reduce the upstream pressure and maintain a constant preset downstream pressure, constantly
responding to upstream pressure & fl ow fl uctuations. When downstream pressure is under preset pressure, the Main
Valve opens to increase it (the Pilot allows the discharge of top chamber). When downstream pressure is above preset
pressure, the main valve closes to decrease it (the Pilot allows the fi lling of top chamber).
In static conditions, with no fl ow, the Main Valve fully closes when downstream pressure is above preset downstream
value. Downstream pressure can slightly increase above preset pressure due to valve response time, so this must be
taken into consideration.
Pressure Reducing Pilot adjustment:
With working mode 2.1 or 3.1:
To increase the preset downstream pressure, turn the Pilot adjusting screw clockwise.
To decrease the preset downstream pressure, turn the Pilot adjusting screw anti-clockwise.
5.3 Requirements at the place of installation
- Aggressive environmental conditions may reduce the life span of the product.
- Consider the interaction between the system and the equipment. Foresee elements to absorb vibrations, pipe dilatations, guides, anchoring and proper support according to the weight of the components.
- The system and operation protocol should be conceived in such a way to avoid cavitation and high velocities (as reference, max. 4 m/s or lower in case of abrasive media). Prevent pulsing fl ow or water hammers, which are very harmful
for valves and the rest of the components.
- Flooding of the product is not recommended.
- Allow enough space for valve installation, operation and maintenance.
- It is recommended to install a proper sized mesh strainer upstream the valve in order to protect seating surfaces from
abrasion or erosion that could lead to seat leakage.
-The installation of a bypass can be of help when a continuous service is needed during maintenance.
- Planners / construction companies or the owner are responsible for positioning and installing products.
6. – COMMISSIONING
Page 5
ATTENTION!
- Before commissioning the valve, check the material, pressure, temperature, fl ow direction and other essential pa-
rameters. Always use the product within the scope of intended service and operating duties.
- Before commissioning, make sure above chapters have been throughly followed.
- It is essential to fl ush the pipe system thoroughly to eliminate all the particles and impurities which could remain in
the pipes and particularly welding residue, chips, tool remains, etc. that could damage the equipment during startup. Ensure that during cleaning of the pipe system, any chemicals used and temperature are compatible with the
valve construction.
- Regional safety instructions should be adhered to.
- T emperatures above 50ºC or below 0ºC may cause personnel injuries if valves are touched. Ensure that the corresponding warning signs are displayed on the valve or surrounding area, or isolate the equipment in case of danger.
- Before commissioning a new plant or restarting it after repairs or modifi cation, always ensure that:
- All work has been completed correctly!
- The valve is in the correct position for its function.
- Safety devices have been attached!
ATTENTION!
- In case of valve seat leakage, the downstream pressure could not be kept in static conditions, so it is important to
foresee a safety device to relieve excess of pressure downstream the valve.
Also under dynamic conditions, in case of bad adjustment, Pilot failure or leakage through Pilot circuit, downstream
pressure could increase above the desired value, so again it is recommended to foresee a safety device to protect
downstream line against overpressure.

- Ensure valve surface is in good condition and retouch coating protection when needed.
- The fi lling, warming-up and starting-up of the system shall be gradual so as to avoid any inadmissible stress. Check for
tightness in valve connections, body/cover union and Pilot circuit body/bonnet union, and stem, and retighten crosswise
and gradually if necessary until leakage elimination. If leakage persists, unions should be inspected, surfaces should be
thoroughly cleaned and new gaskets correctly placed.
- Ensure the existence of gauges or pressure transmitters in good condition to register the pressure.
- Check the Pilot circuit according to given layout.
- Check the correct wiring of the Solenoid Valves and the tightness of their connectors.
- Operate gradually and wait enough time for the reaction of the system to avoid inadmissible stress or water hammers.
- The Main Valve is fi rst isolated from the rest of the system by means of the upstream and downstream isolation valves.
- Open slowly the upstream isolation valve so that the fl uid fi lls up the Main Valve and its circuit.
- Eliminate the air trapped in the top parts of the circuit by loosening the connections.
- Discard blocking or leakage in the Pilot piping.
- Open fully the upstream isolation valve.
- Ensure the Pilot adjusting screw is nearly loosen.
- Open slowly the downstream isolation valve, pressure should remain steady after a few seconds of fl uctuations.
- Set the preset downstream pressure by slowly turning clockwise the adjusting screw (fi rstly loosen its adjusting screw
nut) until reaching the desired value.
- After having set the Pilot, and checked the pressure in the gauge, wait as long as necessary for the system to balance
and make another reading, if necessary repeat the same procedure.
- After fi nishing the adjusting process, tighten back the adjusting screw nut.
- Once the valve installed, make an initial opening and closing operation to check its proper operability.
7. – CARE AND MAINTENANCE
The operator must defi ne maintenance and maintenance-intervals to meet requirements.
- Check for body and seat tightness and valve smooth operation without additional tools. Discard obstructions or blocking
in the Pilot system.
- Check the valve surface inside and outside and retouch coating protection when needed. If advanced corrosion or erosion is observed, double check service and valve features and replace the valve properly.
- In case of body/cover leakage, retighten the bolts in a crosswise, moderate and uniform manner. If leakage cannot be
corrected, dismount the cover, clean sealing surfaces and replace the diaphragm when needed.
- It is recommended to open and close the solenoid valves at least once a day, in order to prevent from solenoid stuck
blocking.
- In case of seat leakage, try to close the Main Valve with the Manual Valve of the Pilot system if any to discard damages
or blocking in the Pilot system, and open the valve if possible to drain deposits or impurities trapped. If problem is not
solved, dismount the valve to inspect diaphragm and body seat and replace them when needed.
After any maintenance work please refer to chapters 5 and 6 for installation / commissioning.
Recommended Spare parts:
Use only original spare parts.
The diaphragm is a typical wear component and should be replaced periodically. Bodies, Pilots, Solenoids, manual valves
or strainers can also get damaged during service. Type and number of each spare part to be stored according to many
factors: service level, valves quantity, etc. In many cases a good choice is to keep complete valves as spare part.
Page 6
ATTENTION!
- In the event of infrequent use, operate the valve as frequently as possible to avoid deposits of dirt and valve
blocking. After long period without use of 4-way manual valve, remove the lever by losening the fi xing screw and
operate with a wrench in case of too much resistance to turn. Then place the lever back taking into account its
relative position
- When using the valve as an end seal, the employers’ liability insurance association specifi es the use of a safety
precaution such as a plug-in disc, blind fl ange, Before starting maintenance work on an end valve with a free stem
end, you must mount a blind fl ange.
- Before disassembling the valve, note chapters 10 & 11.
- When the valve is operated, there is a crushing hazard between the diaphragm and the body.
- Only carry out maintenance work in the pipework when the valve has been secured from operation (in case of
actuator, ensure it has been disconnected from the mains supply and secured from reactivation).
- Check correct position of nameplate and handle with care to avoid personnel cuttings.
- When the valve is operated, there is a crushing hazard between the diaphragm and the body. Ensure the valve
is not under operation in case hands are introduced inside the valve.
