AIR VALVE - 1/8" ANGLE

This 1/8-inch angle steam radiator air vent purges trapped air from a one-pipe steam radiator so steam can fill it, then closes automatically when steam reaches the valve. A straightforward fixed-orifice replacement for worn or noisy angle vents.

Key Features:

• Automatic Air Venting -- Opens to release air on a steam call and closes when steam or heat reaches the valve.
• Fixed Orifice -- Non-adjustable port for standard one-pipe steam radiator venting.
• 1/8 in. NPT Angle Shank -- Threads into the radiator side tapping.
• Direct Replacement -- Swaps for common 1/8-inch angle steam radiator vents.
• One-Pipe Steam -- For low-pressure one-pipe steam radiator service.

Where to Use:

• Building maintenance -- Replacing failed, noisy, or spitting air vents on one-pipe steam radiators and convectors
• Steam system balancing -- Sizing vents by distance from the boiler so radiators heat evenly across the building
• Property heating upkeep -- Seasonal vent replacement in apartment buildings and older steam-heated properties
