b) Assembly
a. The O-rings (ref.12) will have to be mounted on the piston by using a tapered tool that will allow to make
them slide easily into their position. Push the acetal resin rollers (ref.7) into their position, on the piston.
b. Grease the piston (ref.2) and its parts (ref.7and12)
c. Grease the internal surface of the cylinder (ref.1)
d. Place the shaft (ref.4) so that its grooves are in the correct position to receive the pistons and also have
the right rotation direction.
e. Insert the pistons (ref.2) in the wedges (ref.4) and push them in the cylinder simultaneously (ref.1). The
OMAL S.p.A. Scotch yoke system, will prevent the misalignment of the pistons.
f. Reposition the seals (ref.8) in the caps (ref.3) and grease them. Fix the caps to the body by tightening the
screws in a crosswise sequence (ref.16).
g. Apply, to the screws, the tightening torque pointed out in paragraph 5.
8) SPECIAL VERSION
OMAL S.p.A. produces and supplies also special versions of its actuators, for the use in conditions of low
temperature (-50°C) and high temperature (+150°C), for application in explosive atmosphere environments
(
II 2 GD TX X) and others for specific purposes.
9) STORAGE
The OMAL S.p.A. actuators are properly packaged for protection during the dispatch, but they could still
get damaged 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.
