1/8″ Steam Air Vent for Heating Systems
The Everflow RAVHA18A is a chrome-plated steel float-type valve designed to remove air from residential steam heating systems. Its angle-adjustable mount lets installers orient the outlet to suit tight piping layouts. The 1/8″ NPT thread fits standard radiator tappings without adapters. Solid steel construction resists corrosion in hot, humid conditions.
Practical Limits of 1/8″ NPT Steam Service
The 1/8″ connection restricts airflow capacity to small radiators or branch lines; larger mains vents need bigger ports. Float mechanisms can stick if system water carries sediment, so periodic inspection is prudent. Chrome plating withstands normal steam temperatures but may discolor above design limits. California Proposition 65 warnings note lead exposure; wash hands after handling.
Build Quality and Daily Implications
Chrome-plated steel body and float resist rust better than bare iron, extending service life in wet steam. Angle-adjustable mount simplifies alignment on sloped or crowded radiator tappings, reducing install time. Quiet operation means no disruptive hissing during venting cycles. No electrical parts to fail — purely mechanical function suits off-grid or backup-heat scenarios.
