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.

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.
