Maintenance; Special Versions - omal automation DA2880 Installation, Use And Maintenance Manual

7) MAINTENANCE

The OMAL SpA actuator, when installed and used properly, does not require maintenance, under normal
use, as it's provided with sufficient lubrication for standard duration.
Send the actuator directly to OMAL S.p.A. for inspection or extraordinary maintenance
OMAL S.p.A. declines all responsibility for products that are repaired by third parties

8) SPECIAL VERSIONS

OMAL S.p.A. produces and supplies also special versions of its actuators, for applications in low tempera-
ture conditions (-50°C) and high temperature (+150°C), for the use in explosive atmosphere environments
( II 2 GD TX X ) and for other specific uses.
a. External protection.
All versions can be supplied with a different external protection according to the environmental conditions
of the system (for the choice, consult the OMAL S.p.A. catalogue or contact the commercial department).
b. Stainless steel version
For plants of the food industry or chemical sector, OMAL SpA produces a stainless steel version. The body
and all external parts are made of stainless steel AISI316.
c. Normally open spring return version
The normally open spring return version is required in the cases where if there should be a pressure or po-
wer failure, the valve must absolutely remain open. In this version the pistons are inserted in the cylinder
like the ones for the double acting version, the strength of the springs makes the actuator normally open.
ATTENTION
The performance of the normally open Spring Return version, compared to the normally closed Spring
Return one, are very different due to the production differences. For the sizing and choice please contact
the OMAL S.p.A. technical department.
9) STORAGE
The OMAL S.p.A. actuators are properly packaged for protection during the dispatch, but they could still
get damaged accidently during transportation. Before storing them verify that they have not been dama-
ged during the transportation. Keep actuators in the package when storing.
Choose clean sites for storage, not excessively humid and with temperatures between –10 and +60°C. If
the products are to be stored for long periods of time, it is best not to remove them from their protective
packaging.
The actuators have two air ports, plugged with plastic caps, in order to avoid that liquids or other may
enter through during the storage.
If the items will be in storage for a long period of time before installation, it is recommended to maneuver
them periodically in order to avoid that the seals get damaged.
Store the actuators indoors to protect them from dust and moisture.
