The AK-42309-500 Positive Positioner Pneumatic
Relay is used to accurately position an actuator with
respect to signal pressure from the controller. It can
also be used to change the effective spring range of an
actuator and increase the capacity of a controller.
The AK-42309-500 Positive Positioner Pneumatic
Relay is compatible with MK-2690-0-0-1,
MK-2690-0-0-2, MK-3XXX, MK-44XX,
MK-46X1-XXX-0-2, MK-48XX, MK-66XX, MK-68XX,
MK-69XX, MK-7XXX, MK-88XX, and MK-89XX Series
actuators. The AK-42309-500 cannot be used with the
following actuators: M556, M573, M574, M693,
MK-2690-0-0-0, MK-4600-0-0-0, MK-4600-0-0-1, and
MK-12000 Series actuators.
