Gorton No. 5 1/8" Straight Steam Air Vent Valve
This straight-mount vent valve threads directly into a 1/8" male radiator tapping. It is built for one-pipe steam systems and vents air at a rate equal to four ordinary valves. The non-adjustable body is made of steel and rated for 140-240°F operation.
Sustained venting at boiler pressure
Under continuous steam pressure the valve maintains its full venting capacity without throttling back. The fixed orifice does not require field adjustment, so performance stays consistent from cold start through extended heating cycles. Maximum service temperature is 240°F.
Check radiator tapping and system type
Verify the radiator has a 1/8" female thread and that the system is steam, not hot water. The valve is designed for mains near the boiler and warm-room radiators where rapid venting is needed. It will not function on two-pipe or vacuum systems.

Questions about this item
How much heat does the Gorton No. 5 vent valve handle during continuous steam service?
It operates reliably between 140°F and 240°F, so all-day steam cycles stay well within its rated temperature range.
What pipe fitting must already be on the radiator for this valve to thread in?
A 1/8" female NPT tapping is required to accept the valve's 1/8" male thread.
Will the straight body clear the supply pipe on a vintage cast-iron radiator?
The straight mount sits inline with the 1/8" tapping, matching the original profile on most period radiators near the boiler.
