Gorton No. 4 1/8" Angle Steam Air Vent Valve

This Gorton No. 4 angle valve releases air from steam radiators using a 1/8 inch connection. It serves rooms where the thermostat sits and radiators that influence that thermostat. The vapor equalizing design balances pressure during each heating cycle. Condition is new.

Use on thermostat-controlled radiator zones

Install this vent on radiators governing the main thermostat to prevent air locks that skew temperature readings. It suits one-pipe steam systems needing reliable air release at the radiator. Buyers needing straight-pattern vents or larger pipe threads must select a different model. No tools or sealant are included in the package.

Questions about this item

Will the valve seat or float mechanism need periodic replacement on this Gorton No. 4 1/8" angle vent?

The valve uses a simple float and seat design with no replaceable cartridge listed; mineral build-up on the seat is the typical wear point, so cleaning the seat during annual system service keeps it sealing.

What operating limit appears first when this air vent runs continuously on a steam radiator?

The vent is designed for low-pressure residential steam; sustained pressure above the system's normal range will keep the float seated and stop air release until pressure drops back to design conditions.
