Compressed Air Drain Valves

Timer-Operated Compressed
Air Drain Valves

Timer-Operated Compressed Air Drain Valves

Set the electronic timer on these drain valves to open automatically at your specified time interval.

Low-Pressure-Operated
Compressed Air Drain Valves

Low-Pressure-Operated Compressed Air Drain Valves

Each time your compressor cycles and the pressure falls by 20 psi, this drain valve opens to discharge.

Float-Operated Compressed
Air Drain Valves

Also known as drip legs, these drain valves have a float that automatically opens the drain when the bowl begins to fill.

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.

No-Air-Loss Compressed
Air Drain Valves

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.

Other Compressor Drains

Air On/Off Valves

Air On/Off Valves

Manually control these valves to turn airflow on or off.

Hydraulic Valves

Hydraulic Valves

Control the speed, direction, and pressure of fluid in a hydraulic system.

Solenoid On/Off Valves

Solenoid On/Off Valves

These valves withstand rapid cycling for a long service life in applications with frequent opening and closing. They operate on electricity.
