High-Discharge Float-Operated Compressed Air Drain Valves
With a discharge capacity of more than four gallons per minute, these drain valves can handle large compressed air systems. Also known as drip legs, these drain valves have a float that automatically opens the drain when the bowl begins to fill. Install them at low points in your line after separators, dryers, filters, and aftercoolers. Drains can be serviced without removing them from your air line.

No-Air-Loss Compressed Air Drain Valves
Save energy by minimizing the loss of compressed air. Unlike other drain valves, these only open when they're full. They close before the reservoir is completely empty, so no air escapes from the system. Install them at low points in your air line after separators, dryers, filters, and aftercoolers.
Air-powered valves don’t need to be plugged into an electrical outlet. When water raises the float to a set point, these valves open. They have a simple internal design and large openings to prevent clogs. Drain valves with an air pilot require an additional line of air to operate. Install a 5-micron particle filter (sold separately) before the 1- and 3.5-gpm capacity valves.
