4) SAFETY INFORMATION
- The actuator must be used within the specified pressure limits; operation beyond these limits may da-
mage the internal parts of the actuator.
- The actuator operation out of the range of temperatures indicated could damage its internal or external
parts.
- Using the actuator, without the due external protection, may damage it in corrosive environments.
- Before the installation, repair or maintenance be sure that the actuator is not pressurized, disconnect
the air lines and verify that they have vented.
- Do not remove the caps when the actuator is installed online or while it's still pressurized.
- Do not remove the spring cap, this operation may be carried out by qualified personnel only; such ope-
ration could cause personal injuries.
- Before installing the actuator on the valve be sure that the rotation of one is in phase with the rotation
of the other and that the shaft slit position is correct.
- Before installing the actuated valve, carry out a few dry cycles in order to check the proper fitting
between valve and actuator.
- Carry out the installation in compliance with the national local regulations and laws.
- Before installing a pneumatic actuator bearing the marking
2014/34/EU ATEX, carefully read the additional instructions, supplied together with the product, regar-
ding the use in explosive atmospheres.
5) INSTALLATION INSTRUCTIONS
The installation of an actuator allows to open and close a valve, which is installed in a system, without
manual operation, by means of an electric-pneumatic remote control.
The normal sizing of the actuators requires to consider an appropriate safety margin for the breakaway
torque which is necessary for the valve to operate properly. The plant project, physical or chemical cha-
racteristics of the fluids, special environmental conditions, may require an increase of the safety factor to
be applied to the sizing.
To lift the actuator without damaging it, see the below image.
