INSTRUCTION MANUAL
AGO: SCOTCH–YOKE PART TURN PNEUMATIC ACTUATOR
DA2880 - DA8000 - SR1440 - SR4000
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 temperature 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 power 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 damaged 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.
