Automatic air ventilation valve

Application

Installation

The automatic air vent is designed to divert air
accumulations from pipelines and air collectors
of internal building heat supply systems (systems
heating, heat supply of ventilation units, air condi­tioners, collectors, etc.).

When filling the body of the air vent with liquid,
the float rises and closes the air outlet through
the lever. With the accumulation of sufficient
the amount of air in the body (or when the system
is draining, when water begins to be removed
from the pipeline), the float goes down and the air
outlet opens.

Description Type Code no.

Automatic air ventilation valve with built-in non-return valve SSM-AV 088U0945

The automatic air vent should be installed at the
highest point of the piping system or on the air
intake in a vertical position. Between the air vent
and the pipeline (air collector) it is recommended
to provide for the installation of a ball shut-off
valve.

Air vent installation should be done using a
wrench and standard sealing materials. Before
installing the air vent, the piping system must be
flushed. After installing the air vent, the safety cap
located on the device cover must be unscrewed
half a turn.
