    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.

    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—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.
    Electric—Electric 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.
    1/8 Pipe Size Air Pilot and 1/4 Pipe Size Air Pilot—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.
    Contact for Remote Signaling Device—Drain valves with a contact for remote signaling device can be wired to activate a remote alarm if blocked.

    Use the digital display to set these valves to open automatically at precise intervals. 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. They meet NEMA 4 for protection from dirt and washdowns.

    Keep an eye on condensate collecting in your compressed air line. These drain valves have a clear bowl, so you can see inside to inspect the contents. Also known as drip legs, these 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.

    When your compressor turns off, it creates back pressure that opens these valves automatically, allowing liquid to escape. Moisture is atomized as it is discharged through the included muffler, eliminating the need for discharge piping. The muffler also minimizes noise. Install drain valves after coolers, separators, dryers, and filters.

    Image of Product. Front orientation. Drain Valves. High-Discharge Float-Actuated 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.
