2.3 Assembling the Actuator Onto the Valve
2.3.1 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 cannot directly match the actuator
ange in its “standard” conguration. For the biggest actuator models, the actuator ange
can be machined in accordance with the valve ange dimensions.
The yoke has bored with keyways for coupling to the valve stem, the dimensions of which
are according to Bif standard tables SCN6200* and SCN6201*.
