Series HAV

Air Vent

Automatic Vent for

Hot Water

Sizes:

⁄8" and

⁄4"

(3 and 8mm)

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.

• Quick venting design

• Positive shut-off ball check

• Heat resistant handwheel

• Suitable for use with hot water and low pressure

steam systems
