Note:
With only two states returned from the air eliminator,
flow must be completely stopped to purge air. To purge air
by only slowing the rate, a 3 output air eliminator head must
be used.
Note:
When the level drops below Low, the power will be
removed from the digital valves, stopping flow before the air
eliminator is completely drained.
