Attachment To The Control Valve - Mounting Parts And Accessories - Samson 3730-3 Mounting And Operating Instructions

2 Attachment to the control
valve – mounting parts and
accessories
The positioner can be attached either di-
rectly to a SAMSON Type 3277 Actuator or
according to IEC 60534-6 (NAMUR) to con-
trol valves with cast yokes or rod-type yokes
as well as to rotary actuators according to
VDI/VDE 3845.
For attachment to the various actuators, cor-
responding mounting parts and accessories
are required. These are listed with their or-
der numbers in Tables 1 to 5.
On attaching the positioner, it is important
to observe the assignment between lever
and pin position according to the travels
listed in the travel tables.

The tables show the maximum adjustment
range at the positioner. The travel that can
be implemented at the valve is restricted by
the pin position used and additionally by the
actuator spring compression required.
The positioner is standard equipped with the
lever M (pin position 35).
Note!
If the standard mounted lever M (pin posi-
tion 35) is replaced, the newly mounted le-
ver must be moved once all the way as far
as it will go in both directions to adapt it to
the internal measuring lever.
