1.5.1 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.
1.6 Operation conditions
1.6.1 Product location and operation position
EA 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.
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.
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.
1.6.2 Working enviroment
According to valid standard IEC 60 721-2-1, there are delivered these versions of electric actuators:
1) Version „standard“ for type climate temperate
2) Version „tropical wet“ for type climate tropical wet
3) Version „cold“ - for type climate cold
4) Version „tropical dry and dry“ for type climate tropical dry and dry
5) Version „marine“ for type climate marine
6) Version „arctic“ for type climate arctic.
In accordance with IEC 60 364-1, IEC 60 364-5-51 and IEC 60 364-5-55 within valid edition the EA have to
resist external effects and operate reliably:
