AK-42309-500 Positive Positioner Pneumatic Relay
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.
