DVC2000 Digital Valve Controller

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 actuator yoke and the DVC2000, as shown in figure 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 9.

NOTES
ZONE 1: STANDARD GX BONNET AND STANDARD DVC2000 MOUNTING APPLY.
ZONE 2: REQUIRES GX EXTENSION BONNET OR HIGH TEMPERATURE DVC2000 GASKET SET.

Note
The GX extension bonnet option is an alternate way to address the high process temperature influence on the DVC2000. However,
if the extension bonnet is used, the high temperature DVC2000 mounting kit is not required.
