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.

Timer-Operated Compressed Air
Drain Valves with Digital Display

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

High-Pressure Timer-Operated
Compressed Air Drain Valves

These withstand at least double the pressure of our other timer-operated drain valves.

Easy-to-Clean Float-Operated
Compressed Air Drain Valves

An external drain provides quick, easy access for cleaning.

High-Pressure Float-Operated
Compressed Air Drain Valves

Able to withstand up to 400 psi, these have the highest pressure rating of all our float-operated drain valves.

Compact Float-Operated
Compressed Air Drain Valves

Sized right for tight spots.

Easy-to-Monitor Float-Operated
Compressed Air Drain Valves

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.

High-Discharge Float-Operated
Compressed Air Drain Valves

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

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

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.

Steam Traps

Energy-Saving Stainless Steel Steam Traps

Also known as thermodynamic steam traps, these discharge condensate when close to steam temperature for minimal energy loss.

Stainless Steel Steam Traps

Also known as thermostatic steam traps, these increase the efficiency of your radiator by venting cool air.

Sanitary Stainless Steel Steam Traps

Suitable for food, pharmaceutical, and other sanitary environments, these steam traps are made of 316 stainless steel with a Viton® fluoroelastomer O-ring to stand up to frequent washdowns with harsh cleaners and sanitizers.

Sanitary Energy-Saving Stainless Steel Steam Traps

When close to steam temperature, these traps—also called thermodynamic steam traps—release condensate from steam lines to save energy in food, pharmaceutical, and other sanitary environments.

High-Flow Stainless Steel Steam Traps

Also known as inverted-bucket steam traps, these provide near-continuous discharge to accommodate high condensate levels.

Energy-Saving Iron Steam Traps

Also known as thermostatic steam traps, these vent cool air and condensate to increase energy efficiency in your steam lines.

High-Flow Iron Steam Traps

Also known as inverted-bucket steam traps, these provide near-continuous discharge to accommodate high condensate levels.

Brass and Bronze Steam Traps

These steam traps offer good corrosion resistance.
