Dynaquip Controls AD2A 3/4 Auto Drain Valve 115V
Automatic timed drain valve removes condensate from compressed-air systems at up to 6.0 gal per cycle with adjustable intervals from 1 min to 14 days
- Automated drainage prevents moisture buildup with a 6.0 gal/cycle purge rate
- Adjustable cycle timer from 1 min to 14 days fits any maintenance schedule
- NEMA 4 enclosure protects internal components in harsh industrial environments
- Lead-free brass body handles 200 psi maximum pressure for long service life
- 115 V AC operation draws only .83 A for efficient timed draining
What this valve does
The Dynaquip Controls AD2A is a timed electric auto drain valve built for compressed-air systems. It removes condensate automatically so operators do not have to open manual drains. The unit suits workshops and light-industrial plants that run on 115 V mains power.
The spec that decides fit
The valve connects with 3/4 in pipe and drain ports and is rated for 200 psi maximum pressure. It operates on 115 V, 60 Hz supply drawing 0.83 A and functions between 35 and 165 degrees F. NEMA 4 enclosure rating protects the internals from splashing water and dust.
What the included parts change
Supplied 1/4 in bushings let you adapt the valve to smaller drain lines without extra fittings. Adjustable cycle timer runs from 1 min to 14 days with a fixed 7 sec purge, and the lead-free brass body meets potable-water material requirements.

Questions about this item
How much condensate does the 6.0 gal/cycle drain rate actually remove in a typical compressor setup?
Each purge opens the valve for 7 seconds and expels up to 6.0 gallons, so a single cycle can clear a large receiver or multiple smaller traps without manual intervention.
What does the 115 V, 60 Hz, 0.83 A rating mean for wiring the valve into an existing compressor circuit?
The coil draws 0.83 A at 115 V AC, 60 Hz, so it can share a standard 15 A compressor branch circuit and only requires a NEMA 4-rated junction box for the enclosure.
Will the 3/4 in pipe and drain ports with included 1/4 in bushings fit my current receiver outlets?
The valve body has 3/4 in NPT inlet and outlet; the supplied 1/4 in bushings let you reduce either port to match smaller receiver tappings without extra fittings.
