Required Mounting Parts And Accessories - Samson 3730-2 Mounting And Operating Instructions

Attachment to the control valve – Mounting parts and accessories
Attachment according to IEC 60534-6
(NAMUR rib or attachment to rod-type
yokes) and to rotary actuators
The positioner requires an additional port for
the exhaust air that can be connected over
piping. An adapter available as an accesso-
ry is used for this purpose:
Threaded bushing
(M20 x 1.5)
Note
The adapter uses one of the M20 x 1.5 con-
nections in the housing which means only
one cable gland can be installed.

Should other valve accessories be used
which vent the actuator (e.g. solenoid valve,
volume booster, quick exhaust valve), this ex-
haust air must also be included in the purg-
ing function. The connection over the adapt-
er at the positioner must be protected with a
check valve (e.g. check valve G ¼, order no.
8502-0597) mounted in the piping. Other-
wise the pressure in the positioner housing
would rise above the ambient pressure and
damage the positioner when the exhausting
components respond suddenly.
