Description
The DAT Double Acting Throttling Device is used to throttle exhausting air and allow large amount of air
to enter the system in a vacuum condition.
The DAT is used to regulate (adjust) the air exhaust on pump start-up to attain a smooth pressure
transition between the exhausting air and the operating pressure. During pump shut-off, the device will
automatically allow a large amount of air in during vacuum to protect against pipe collapse.
NOTE: The DAT is not a stand-alone device and cannot be installed directly to the pipeline. The
DAT must be installed in the outlet port (top) of the Air/Vacuum Valve or Combination Air
Valve.
