10) TROUBLESHOOTING
11) DISPOSAL OF PRODUCTS AT THE END OF THEIR LIFE CYCLE
The OMAL products are designed so that when they are at the end of their life cycle they can be completely
disassembled, separating the different materials for the proper disposal and/or recovery. All materials have
been selected in order to ensure minimal environmental impact, health and safety of personnel during their
installation and maintenance, provided that, during use, they are not contaminated by hazardous substances.
The personnel in charge of the product disposal/recovery, must be qualified and equipped with appropriate
personal protective equipment (PPE), according to the product size and the type of service for which the
device was intended. The management of waste generated during the installation, maintenance or due to
the product disposal, is governed by the rules in force in the country where the product is installed, in any
case, the following are general guidelines:
- The metal components (aluminum/steel) can be restored as raw material;
- Seals/sealing elements (PTFE, PEEK, NBR, EPDM, FKM ...), as contaminated by fluids from other materials
and lubrication, must be disposed of.
- The packaging materials that come with the product, should be transferred to the differentiated collection
system available in the country.
12) DECLARATION OF CONFORMITY
The OMAL S.p.A. actuators have been designed, manufactured and tested to meet the requirements of the
following European standards and are marked, where provided, with the relative CE marking of conformity:
- 2006/42/EC Directive “Machinery”;
-
2014/34/EU
Directive “Equipment and protective systems intended for use in potentially explosive atmo-
spheres” (ATEX).
- Regulation (EC) No 1907/2006 and successive Concerning the Registration, Evaluation, Authorization and
Restriction of Chemicals (REACH)
POTENTIAL EFFECT OF FAILURE
POTENTIAL CAUSE OF FAILURE
SOLUTION
Loss or reduction of the supplied
torque
Lack of supply
Verify that the actuator has been con-
nected properly
Air supply not enough to produce
the required torque
Verify that the supply pressure value
corresponds to the functioning requi-
rements (See actuator data plate).
Air leakage from the seals
Verify that the screws are completely
tightened
Leaks from the stem upper or
lower seals
Stem O-ring seal damaged
Contact OMAL S.p.A. for repair
Damages on the body
Shaft damaged
Leakage from cylinder caps
Seals damaged
Replace the seals (see “Maintenance”
chapter)
Leakage from the ports after
maneuver
Piston sealing damaged
Replace the piston seals (see “Mainte-
nance” chapter)
Cylinder body damaged
Contact OMAL S.p.A. for repair
Insufficient rotation angle
Increase of valve maneuver torque
Verify the valve release torque and
possibly replace with a new one
Air supply not enough to produce the
required torque
Increase the air supply
Mechanical stop (if there) not duly
adjusted
Adjust the stops by increasing the
stroke
Wrong connection between the
actuator supply hole and the valve
stem
Check the connection and size of the
adapter between the valve and the
actuator
