AIR VALVE - 3/4 X 1/2 STRAIGHT

This large 3/4-inch by 1/2-inch straight steam air vent moves a high volume of air, purging steam lines so steam advances quickly and the system heats evenly. It closes automatically as pressure builds to keep steam in the piping.

Key Features:

• High-Capacity Venting -- Larger body clears far more air than a standard radiator vent.
• 3/4 in. x 1/2 in. Straight -- Straight shank for higher-flow venting points.
• Automatic Close -- Closes as system pressure rises to hold steam in the line.
• Fixed Design -- Non-adjustable; for low-pressure one-pipe steam.
• Metal Body -- Durable body for steam service.

Where to Use:

• Building maintenance -- Replacing failed or noisy air vents on one-pipe steam radiators and mains
• Steam system balancing -- Venting air so steam reaches radiators quickly and heats evenly
• Property heating upkeep -- Seasonal vent replacement in apartment buildings and older steam-heated properties
