1.INTRODUCTION
Throughout this manual there are a number of HAZARD
WARNINGS that must be read and adhered to in order to
prevent possible personal injury and/or damage to equi-
pment. Three signal work “DANGER”, “WARNING” and
“CAUTION” are used to indicate the severity of a hazard,
and are preceded by the safety alert symbol.
Danger Denotes the most serious hazard and is
used when serious injury or death WILL result from misuse
or failure to follow specic instructions.
Warning Used when serious injury or death MAY
result from misuse or failure to follow specic instructions.
Caution Used when injury or product/equipment
damage may result from misuse or failure to follow specic
instructions.
Caution It is the responsibility and duty of
Warning all personnel involved in the installation,
Danger operation and maintenance of the equi-
pment on which this device is used, to fully understand the
procedures by which hazards can be avoided.
The compatibility of the product is the responsibility of
the person who designs the equipment or decides its
specications.
Only personnel with appropriate training should operate
machinery and equipment.
Do not service or attempt to remove the machinery or
equipment until safety is conrmed.
2.DESCRIPTION
The Flow regulators are generally used to control the
outow of a media. A typical application is the speed control
of an actuator. A complete range of needle valves and ow
regulators provides a variety of choices between uni or
bidirectional versions and different precision features.
3. OPERATION
Adjusting the speed of actuator by opening the needle
slowly after having closed it completely. Loose of needle
valve may cause unexpected sudden actuator extension.
Turning clockwise the adjustment knob the quantity of ow
passing through the regulator decreases. Turning the adju-
sting knob counter clockwise, you increase the quantity of
ow through the ow regulator.
When needle valve is turned counter‐clockwise it is open
and cylinder speed increase.
The ow rate is adjusted in the direction indicated by the
arrow. In the direction opposite the ow, typically to cylinder
supply, is free and not adjusted.
If the cylinder pressure falls below the inlet pressure, the
pressure differential on the diaphragm will close the exhaust
Port 3, preventing further exhaust.

Medium: compressed air or inert gases, ltered, lubricated
and not lubricated
Port thread: 1/8”, 1/4”, 3/8”, 1/2, 3/4”, 1” NPT

Materials: Body - SS316L or Aluminum alloy
Internal parts: SS316 or galvanized steel (all vers)
6.TRANSPORTATION & STORAGE
The preferred storage location is a clean, dry and protected
warehouse. If the components have to be stored outside,
precautions should be taken to keep valves clean and dry.
For storage temperatures, refer to the table in paragraph
“TECHNICAL FEATURS”.
To avoid contamination of impurities during the storage period,
don’t remove thread protection caps; remove them just before
the installation phase.
7. INSTALLATION
Warning Before performing any work, read this ma-
nual and study all gures. Assure yourself that you understand
and you can do what is required in each step. Failure to follow
these instructions may affect quick release valve operation and
may result in exposure to personal injury.
Before installing the valve, set and block the machine or equi-
pment in a secure position; close the air shutoff valve and
exhaust air from air lines and disconnect all electrical power.
• Please operate within the range of specied capacity in the
manual. If exceeded, the product can be damaged and may
result in serious damages and accidents.
• Make sure to use pressure reading device when setting pres-
sure level.
• Install in correct order when other devices are being operated.
8. MOUNTING
• Any direction
• With air ow in direction of arrow according to label.
• Connect piping to proper ports using pipe thread sealant on
male threads only. Do not allow sealant to enter interior of
unit.
9. TESTING
• Apply inlet pressure, then turn adjustment (1) clockwise to
decrease and counterclockwise to increase outlet pressure
setting.
• Once required pressure is achieved tighten locknut (2) to
lock setting.
NOTE
Warning In option has a “Anti-tamper system” to
avoid the un-authorized modication of the setting. This option
is mandatory for safety related applications.
10. MAINTENANCE
Warning Before performing any work, read this ma-
nual and study all gures. Assure yourself that you understand
and can do what is required in each step. Failure to follow these
instructions may affect quick release valve operation and may
result in exposure to personal injury.
Before uninstalling the valve, set and block the machine or
equipment in a secure position; close the air shutoff valve and
exhaust air from air lines; disconnect all electrical power.
• Shut off inlet pressure. Reduce pressure in inlet and outlet
lines to zero.
• Turn adjustment screw fully counter clockwise.
• Disassemble in general accordance with the item numbers
on exploded view.
A.Ordinary maintenance
Caution The RF should be periodically checked for
proper functioning:
• Clean the RF from impurities and dirt;
• Visually check of the integrity of the body of RF;
• Check that there aren’t leakages;
• Check the correct functionality of the RF.
C. Assembly/Disassembly
• Assemble/disassamble the unit as shown on the exploded
view.

11. MARKING ACORDING TO 2014/34/UEAtex
For using these equipment in potentially explosive
atmospheres, it is recommended - for the installation and the
maintenance operation - to use tools and instruments that
can produce only a single spark (for instance: screwdrivers,
spanners). Avoid use of tools that can produce sparks like
disk saw or grinder
Action must be taken to put to earth the units through a
suitable connection, checking that all the metal components
(ttings and pipe line) have to be equitable potential.
Equipment have to be installed in the corresponding zone
according to the marking.
