Description

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.
