Whether
you need the simplicity of a basic valve or the flexibility
of added features, the Sentinel Series is your solution. Choose
from two models, plus different options to fit the level of
adjustment and controls you need
MDV-400I
For dependable draining at consistent intervals choose Sentinel
model MDV-400I. A power on LED and test button are conveniently
located on the top cover. To reset the valve, simply adjust
the switches on the internal circuit board.
MDV-400L
If you prefer an easy-to-use keypad for convenient timing
adjustments and a handy LCD cycle status readout, choose
Sentinel model MDV-400L. You'll never wonder "when
it's set to fire again" with its continuous, clear
countdown display of the remaining cycle or drain open times.
Added features include external test and valve fault functions,
both with LCD readout.
The Sentinel Series is also offered with a stainless steel
valve, as well as several sizes and voltage options.
Zero Loss with Demand Draining:
For draining based on actual liquid levels, the Sentinel
can operate in response to a liquid level sensor. When used
as a demand drain, the Sentinel drains only liquid, eliminating
air or gas loss and noise.
Reliably Manage Any Fluid
with Ease:
For the most dependable, "round the clock" draining,
install Van Air Sentinel Series drain valves.
The Sentinel's heavy-duty ball valve can manage virtually
any fluid in a wide variety of uses, including cooling towers,
portable installations, process tanks, separators, compressed
air dryers and general condensate management.
With a high-quality, two-piece ball valve that resists clogging,
the Sentinel provides maximum fluid flow and long-term reliability.
Depend on it for nearly any fluid service.
