It is recommended to have after-guarantee service performed by the service department of the
production plant, or by a contracted service centre.
1.4.1 Lifetime of actuators
The lifetime of an electric actuator (EA) is at least 6 years.
EA used for closing mode (closing valves) comply with the requirements for at least 15,000 working
cycles (cycle C – O – C: for part-turn EA)
EA used for regulating/modulating operation (control valves) comply with the below stated numbers of
operating hours at the total number of 1 million start-ups:
Switching frequency
max. 1,200 [h
-1
] 1,000 [h
-1
] 500 [h
-1
] 250 [h
-1
] 125 [h
-1
]
Minimal lifetime expectancy – number of operating hours
850 1,000 2,000 4,000 8,000
Time of net operation is min. 200 hours, max. 2,000 hours.
Lifetime at operating hours depends on loading and switching frequency.
Note : High switching frequency does not ensure better regulation. Setting of regulation parameters
should be therefore made with the inevitably necessary switching frequency needed for the process in
question.
1.5 Operation conditions
1.5.1 Product location and operation position
Electric actuators may be installed and operated in enclosed locations of industrial facilities
with no temperature and moisture regulation, protected from direct climatic effects (such as
direct sunlight). Moreover, special “marine” versions may be used in waste water treatment
applications, water management, selected chemical applications, tropical environments and
coastal areas.
Installation and operation of EA is possible in any position. Vertical position of output part axis and
with the control part above the valve is usual.
Warning:
When the EA is installed in open air, it must be sheltered lightly to protect is against direct
effects of atmosphere.
When installed in the areas with relative humidity more than 80%, in open air under a shelter is
needed to connect the space heater directly – without a thermal switch.
1.5.2 Operation Environment
CLIMATE GROUPS AND TYPES
According to standard IEC 60 721-2-1:
EA have to resist external effects and operate reliably:
• in climatic conditions for the group / type of climate:
- version „standard“- for climate group Restricted (R) + /Warm temperature (WT), Warm Dry
(WDr), Mild Warm Dry (MWDr) and Extremely Warm Dry (EWDr) with
corrosion resistance C3 resp. C4 (EN ISO 12944-2), with temperatures
-25°C to +55°C
- version „cold“ - for climate group Moderate (M) / Cold Temperate (CT), Warm
Temperate (WT), Warm Dry Temperate (WDr) and Mild Warm Dry
(MWDr) with corrosion resistance C3 (EN ISO 12944-2), with
temperatures -40°C to +40°C
- version „universal“ - for climate group General (G) / Cold (C), Cool Temperature (CT),
Warm Temperature (WT), Warm Dry (WDr), Mild Warm Dry (MWDr),
Warm Damp (WDa) and Warm Damp Equable (WDaE) with corrosion
resistance C3 (EN ISO 12944-2), with temperatures -50°C to +40°C
