Description
The DUNGS DMA actuator drives CCW from 0° to 90° via a 4 - 20 mA input signal. The DMA
is available in three different fixed speeds: 6, 12, and 30 seconds. The DMA has one
independent, field adjustable auxiliary SPDT switch and two field adjustable end of travel
switches. 4-20 mA feedback can be used to drive a slave motor (3 actuators maximum) in
parallel. Maximum stroke (Y Max; span) is adjustable from 25Ý to 90Ý, and minimum stroke
(Y min; zero) is adjustable from 0Ý to 75% of set span.

Application
When mounted on the DUNGS DMK butterfly control valve, the DMA is used to automatically
modulate the amount of natural gas, butane, propane and/or air supplied to the burner.
