SKU CH-DR9T-ZK9QH

Automatic drain valve removes condensate from compressed-air systems with adjustable cycles from 1 minute to 14 days

  • Adjustable drain cycle from 1 minute to 14 days for flexible maintenance scheduling
  • Removes 7.7 gallons per cycle to reduce manual draining workload
  • NEMA 4 enclosure protects internal components in wet or dusty environments
  • Lead-free brass body ensures safe operation with potable water systems
  • Operates on standard 115 V AC power at 60 Hz for simple installation

Dynaquip Controls Auto Drain Valve

This timed electric valve removes condensate from compressed-air systems automatically. It fits 1 in pipe and drain connections and operates on 115 V AC power at 60 Hz. The NEMA 4 enclosure protects internal components in harsh environments. Adjustable cycles let maintenance teams match drainage to actual demand.

Suited for plants needing hands-free condensate

Facilities that run continuous compressed-air lines benefit from the programmable 1 min to 14 day cycle range. The 7.7 gal per cycle capacity handles moderate flow rates without overflow. Operations requiring higher pressure than 200 psi or voltages other than 115 V should select a different model. Buyers who need a larger port size must look elsewhere.

Brass body and bushings simplify installation

Lead-free brass construction resists corrosion from moisture and contaminants. The package includes 1/4 in bushings for adapting to smaller drain ports. A fixed 7 second purge time clears the valve seat reliably each cycle. No additional software or electronic accessories are supplied or required.

Questions about this item

What power supply do I need for the 115 V auto drain valve?

The valve runs on 115 V AC at 60 Hz and draws 0.83 A, so a standard 115 V outlet on a circuit rated for at least 1 A is sufficient.

Can the 1 in pipe and drain ports connect to my existing 1 in compressed-air line?

Yes, both the inlet and outlet are 1 in NPT, and the kit includes 1/4 in bushings for adapting to smaller fittings if needed.

How do I confirm the adjustable drain cycle is operating correctly after installation?

Set the timer between 1 minute and 14 days, then watch for the 7-second purge every cycle; the NEMA 4 enclosure LED indicates power is live.
