3/8" Straight Air Eliminator

The Gorton No. 1 valve removes trapped air from steam heating systems through a 3/8-inch straight connection. It installs at the end of steam mains to vent air automatically during system operation. Plumbers and heating technicians use it to improve heat distribution in residential and commercial steam installations.

Automatic venting during steam cycles

The valve opens to release air when steam enters the system and closes against steam pressure once air is purged. This thermostatic action maintains system pressure without manual intervention. Normal operation vents air quietly at the end of each heating cycle with no electrical power required.

Threads into 3/8" pipe at main endpoints

The straight male thread connects directly to standard 3/8-inch steam piping at the end of supply mains. Installation requires one unit for short mains or warm-side runs and two to three units for long mains or cold-side runs. No external controls, wiring or separate air lines are needed for operation.

Questions about this item

How do I install the Gorton No. 1 3/8" air eliminator on a steam main?

Thread the 3/8" straight connection onto the end of the main; use one vent on short or warm-side mains, two or three on long or cold-side mains, or substitute a No. 2 vent for larger buildings.

What maintenance will the Gorton No. 1 3/8" steam air vent valve require?

Periodically check that the vent opens and closes freely; clean or replace the unit if steam leaks or air fails to vent during system start-up.

What is the first limit reached by the Gorton No. 1 3/8" air eliminator under sustained steam service?

The 3/8" connection size limits the maximum airflow capacity, so very long or high-capacity mains may need multiple vents or a larger No. 2 unit.
