Mounting on GX Actuators

The DVC2000 digital valve controller mounts directly
on the GX actuator without the need for a mounting
bracket.
However, in applications where the process
temperature exceeds 80_C (176_F), it may be
necessary to apply an insulating gasket between the

2-8, The heat conducted from the process line will
transmit through the valve body and actuator and
ultimately to the DVC2000. Temperature seen at the
DVC2000 is a function of the ambient temperature as
well as the process temperature. Guidelines on when
to apply the high temperature gasket set are shown in
figure 2-9.
