Steam system air venting

The Gorton No. D valve releases trapped air from steam lines and radiators through a straight 1/4-inch connection. It is built for installations where a large volume of air must be expelled quickly. The unit vents at a rate equal to 27 ordinary air valves.

Vapor equalizing limit

This model is designed for vapor equalizing duty and is not rated for hand-fired systems unless the radiator supply valves remain open continuously. Using it outside that constraint can prevent proper venting and affect system balance.

Thread and pressure check

Confirm the piping uses a compatible 1/8-inch connection before ordering. Verify the operating pressure and temperature of the existing steam system match the valve's intended service range.

Questions about this item

Should I choose the No. D 1/4" straight vapor equalizing valve or a different size for a main venting location?

The No. D model is built for spots where a large amount of air must be vented, making it suited for main venting points on steam systems.

What does the venting capacity equal to 27 ordinary type air valves mean once the valve is installed?

It means this single unit can discharge the same volume of air as twenty-seven standard vents, clearing mains quickly so steam reaches radiators faster.

How does the 1/8" connection affect installation on a 1/4" tapping?

The valve body is 1/4" straight pipe thread for the system tapping, while the 1/8" outlet accepts a nipple or elbow for piping the discharge away.
