The HAV Hot Water Vent is designed for automatic or
manual air release on baseboards, convectors, radia-
tors, and high points in piping systems.
The HAV valve utilizes moisture retaining discs within
the body which vary in volume when they change
from a wet to a dry condition. As the discs dry, they
allow air to escape from the system and when wet,
provide a positive shut-off.
