Application

The Gorton No. 4 steam air vent valve is a 1/8 inch straight vapor equalizing component designed for residential steam heating systems. It installs on radiators located in the same room as the thermostat or on radiators that directly influence thermostat operation. The valve vents air from the radiator so that steam can enter and heat the space evenly.

Thermals noise and power

This mechanical valve operates without electrical power and produces no noise or heat of its own. It responds to steam temperature by closing automatically when steam reaches the vent, allowing the radiator to fill completely. The brass construction withstands normal steam system pressures and temperatures without external energy input.

Questions about this item

How do I install the 1/8" straight vapor equalizing steam air vent valve on a radiator, and what step is often done incorrectly?

Apply thread sealant to the 1/8" male threads, thread the valve straight into the radiator tapping by hand, then tighten gently with a wrench on the hex flats; the common error is over-tightening, which can crack the casting or strip the fine threads.

What maintenance or replacement will the No. 4 steam air vent valve need over time?

The valve's internal float and needle mechanism should be inspected each heating season; mineral deposits can prevent proper venting, so clean the orifice with a fine wire or replace the unit if the seat is worn or the float fails to rise.
