Timer-Actuated Compressed Air Drain Valves


Brass Housing—IP65, NEMA 4 Enclosure Rating	Brass Housing—NEMA 1 Enclosure Rating	Brass Housing—NEMA 4X Enclosure Rating

Set the electronic timer on these drain valves to open automatically at your specified time interval. They’re excellent for compressed air systems with high oil content because they resist clogging when water, oil, and sediment combine to form sludge. Install drain valves after separators, dryers, filters, and aftercoolers to collect and remove water from your air line.

NEMA 4 Enclosure Rating—Drain valves that meet NEMA 4 are rated for protection from dirt and washdowns.

NEMA 4X Enclosure Rating—Drain valves that meet NEMA 4X are rated for protection from dirt, washdowns, and corrosion.

Strainers—Install strainers before drain valves to prevent damage from debris in your pipeline.
