Installation
Section 2: Installation
2.3 Storage
If the actuator needs storage, before installation follow these steps:
• Place it on a wood surface in order not to deteriorate the area of valve coupling.
• Make sure that plastic plugs are present on the pneumatic and electrical
connections (if present).
• Check that the cover of the control group and of the limit switch box (if any) are
properly closed.
If the storage is long-term or outdoor:
• Keep the actuator protected from direct weather conditions.
• Replace plastic plugs of pneumatic and electrical connections (if any) with metal
plugs that guarantee perfect tightness.
• Coat with oil, grease or protection disc, the valve coupling area.
• Periodically operate the actuator (Section 3.3).
2.4 Actuator Assembly on the Valve
2.4.1 Types of Assembly
For coupling to the valve, the housing is provided with a ange with threaded holes
according to Bif standard tables (SCN6200; SCN6200-1; SCN6201; SCN6201-1). The
number, dimensions and diameter of the holes are made in accordance with ISO 5211,
but for actuator models 0.3 to 6 the holes are drilled on the centreline in order to allow
an easier assembly of an intermediate ange, when required. This intermediate ange
(or spool-piece) can be supplied when the valve ange can not directly match the actuator
ange in its “standard” conguration. For the biggest actuator models, the actuator ange
can be machined in accordance with the valve ange dimensions.
