Release pressure in the line between a compressor and an air storage tank, making start-up easier on the motor. These valves open to allow flow into the tank and close when flow stops or reverses direction, preventing air from escaping the tank when the air compressor is not running.

Use the digital display to set these valves to open automatically at precise intervals.

An external drain provides quick, easy access for cleaning.

Sized right for tight spots.

With a discharge capacity of more than four gallons per minute, these drain valves can handle large compressed air systems.

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.
