Veri-Rite steam air vent - how it works - the good, bad and the ugly

This video takes an in-depth look at the Vent-Rite #1 (Vari-Rite) adjustable steam air vent. It breaks down the internal mechanics, explains how to use the adjustable dial, and gives an honest take on its performance.

What You’ll Learn:
-- How Steam Air Vents Work: Understand the basic physics of how these valves allow air to escape so steam can fill your radiator, and how they shut once they sense heat [00:44].
-- Inside the Vent-Rite #1: A look at the internal metal bellows and the "needle" mechanism that regulates air flow [01:51].
-- Adjusting the Venting Rate: Learn how to use the bottom dial (numbered 1–8) to control how fast a radiator heats up [02:57].
-- The "Tongue" Feature: Why the small metal strip at the base of the vent is essential for draining condensate back into the radiator [04:23].

The Good, The Bad & The Ugly:
-- The Good: High reliability and low failure rates compared to other brands. It also handles condensate well, meaning less "gargling" noises [06:48].
-- The Bad: The venting process can be relatively loud (a "whistling" sound) because of the small opening [06:02].
-- The Ugly: The internal metal bellows can make a distinct "popping" sound when it expands and contracts, which might be annoying in a quiet room [07:13].

Final Verdict: Despite some noise quirks, "thumbs up" for its solid construction and consistent performance in balancing steam systems.
