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.

Electric-powered valves have a sensor. When condensate inside the valve rises to the level of the sensor, the valve opens to drain. Valves detect when they’re blocked—they automatically open and close to attempt to remove the blockage and sound an alarm if they’re still blocked. Drain valves with a contact for remote signaling device can be wired to activate a remote alarm if blocked.
