AIR VALVE - 1/8" STRAIGHT VARIVENT

This 1/8-inch straight steam radiator air vent has an adjustable venting rate, letting a technician balance heat across a one-pipe steam system by tuning the air-release speed at each radiator. It vents air on a steam call and closes when steam reaches it.

Key Features:

• Adjustable Venting Rate -- Dial the air-release speed to balance heat room by room.
• Automatic Close -- Closes when steam or heat reaches the valve to keep steam in the system.
• 1/8 in. NPT Straight Shank -- Threads into the radiator or convector vent tapping.
• System Balancing -- Slow the rate on near radiators, open it on far ones for even heat.
• One-Pipe Steam -- For low-pressure one-pipe steam service.

Where to Use:

• Building maintenance -- Replacing failed or noisy radiator vents on one-pipe steam systems
• Steam system balancing -- Dialing the venting rate room by room to even out heat between near and far radiators
• Property heating upkeep -- Tunable vents for apartment buildings where rooms heat unevenly
