15.4 Control Valve and Actuator
If the valve is o n site th en the necessary connections between
valve and separator are fitted. All other parts are delivered sep-
arately (e.g. connection bolts and flange seals).
Only actuators which are suitable and certified for steam regula-
tion may be used.
Actuators must have a fail-sa fe function in order to prevent an
uncontrolled over-humidification in the case of a power failure.
Dirt between the valve face and cone pre vent p roper closing.
Therefore install a filter directly in front of the separator.
Warning:
Control air for pneumatic actuators must be free from
oil and humidity.
If control valves and actuators are part of the delivery then oper-
ating and installation instructions are present.
Customer is responsible for checking steam injection humidifier
compatibilty if control units from other manufacturers are used.
