SAFEGUARDS
GENERAL NOTICES
Beside the rules here below listed the plant
manager must meet the regulation in force
concerning safety and health of workers in
jobsites.
Qualified staff only must be used to operate on the
valve.
The Company rejects any responsibility for
personal injury and damages to equipment
imputable to improper operation, use of non
original spare parts or repairs executed by
unauthorised staff.
Transportation must be performed utilising original
packing up to job-site.
The Company rejects any responsibility for
damages occurred to things and people due to
packing because of having been tampered with.
USE AND MAINTENANCE
WARNING DANGER
Maximum allowable pressure is 6 bar.
To avoid internal parts damage maximum
working pressure is 4.1 bar.
Pay attention to the stem connector and levers
connected to the stem, if any.
WARNING DANGER
Never approach your hands to stem and levers
even when the valve is still, unless air supply
is cut off and spring is released: risk of
personal injury.
When an air tank is supplied together with the
actuator, verify that the nominal pressure of the
connected compressed air line is lower than the
design pressure reported on the air tank plate.
Otherwise, verify that the maximum flow entering
into the air tank is lower than the value reported on
the certificate of the installed safety valve.
DISASSEMBLY
Stick to instruction manual when disassembling
the actuator, even partially.
WARNING DANGER
Ensure that pneumatic connection are not
pressurised before disassembling them.
LIFTING AND HANDLING
When lifting use eyebolts, if any, otherwise sling
the valve body.
WARNING
Valve-actuator assembly can be lifted by means of
eyebolts provided on the actuator only if
expressively stated in special plate.

1-X-290 SERIES LONG STROKE MULTISPRING PNUEMATIC ACTUATORS
INSTRUCTION MANUAL - USE - MAINTENANCE
1. ACTUATOR INSTALLATION
1.1. The air signal supply of the actuator, or of the
positioner, which it may be supplied with, must
be connected with the controller outlet by pipes
of copper or other stainless materials.
1.2. Internal diameter of supply tube must be in
accordance with actuator air connection.
1.3. Bear in mind that, for valves without positioner,
the higher is the distance between valve and
positioner the higher must be the pipe diameter.
1.4. “SERTO” quick joints are recommended, which
allow to connect pipes without welding or
threading.
1.5. Deburr pipe ends and flush pipes by
compressed air before connecting actuator or
positioner air outlet with the controller.
1.6. Finally supply compressed air into the piping
and check any connection for leakage by suds.
