Timer-Operated Compressed Air Drain Valves
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.
Drain valves that meet NEMA 4 are rated for protection from dirt and washdowns. Drain valves that meet NEMA 4X are rated for protection from dirt, washdowns, and corrosion.
Install optional strainers before drain valves to prevent damage from debris in your pipeline.

Back-Pressure-Operated Compressed Air Drain Valves
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.

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.
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.

Automatic-Drain Compressed Air Separators
Housing with
External Drain
A float-operated drain valve on these separators automatically opens when the bowl begins to fill. The first step in water removal, use one of these separators to remove the large amount of water as compressed air cools, preventing equipment damage and wear caused by moisture. Install in your air line after compressors and aftercoolers.
Separators with a sight glass allow you to see inside the bowl to monitor contents.
Separators with an external drain provide easy access for cleaning.

Compressed Air Separators for Oil Removal
In addition to removing large amounts of water, these separators also remove particles and oil droplets. Place them after your compressor and aftercooler, or at the point of use in applications that don't require an aftercooler. They have an automatic drain to discharge the moisture.

Timer-Operated Air On/Off Valves
Install these valves on your air storage tank outlet—at the end of the day, they automatically close to save energy. While in the off position, the tank stays pressurized so the compressor doesn't run when you don't need it to, even if there are small leaks from pipe fittings, drip legs, and other downstream connections. Also known as solenoid valves, these valves actuate when voltage is applied to the electrical connection. They operate on a timer that can be programmed to work with a regular schedule, but they also have a manual override if your schedule changes. They gradually open to prevent system damage from suddenly starting flow.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Drainage Valves
Also known as stop cocks, install these valves on your tank for easy draining.
Valves with external seal are for higher flow applications than valves with an internal seal.
