NOTICE
Inconstant temperatures
Performance of the valve may deteriorate.
– Actuate valve only after the bake-out temperature has been stable for two
hours.
– If valve must be actuated during bake-out, make sure that the heating or
cooling rate does not exceed 10 °C per hour in the temperature range
from 100 °C to 200 °C (version with compact actuator).
from 100 °C to 300 °C (version with extended actuator).
– Make sure that the temperature differences over the whole body do not
exceed 30 °C.
