Description
The "Saar" D-020 Combination Air Valve combines
a Kinetic large orifice and an Automatic small orifice
in a single body. The valve is specially designed
to operate with liquids carrying solid particles such
as wastewater and effluent.
The "Saar" D-020 combination air valve discharges
air, gases and vapor during the filling or charging
of the system and while operating under pressure and
admits air to the system while being drained.
The valve's unique design guarantees complete separation
between the liquid and the sealing mechanism and provides
optimum work conditions.
Operation
The valve is specially designed to operate with liquids
carrying solid particles such as sewage and effluent.
It provides separation of the liquid from the sealing
mechanism. The air/gas gap separation is sustained
under pressure up to 16 bar by a conical body shape
and under vibrations by a spring loaded joint.
Kinetic component - the valve must discharge air,
gas and/or vapor at high velocity during filling of
the system and admits air during its drainage.
The valve should be designed to prevent premature
closing and continue to discharge air, gas and/or
vapor up to 0.8 bar (11 psi) differential pressure.
Automatic component - the valve will release accumulated
air, gas and/or vapor from the system, while the system
operates under pressure. It will have a large
dimensional orifice, at least 12 sq. mm, which is
less susceptible to obstruction by debris.
Pressure
0.2 - 16 bar (3 - 230 psi)
Testing pressure: 25 Atm (350 psi)

Description
The S-020 Automatic Air Release valve discharges accumulated
air, gas and/or vapor form liquids that carry solid
particles, such as sewage and effluent, in systems
operating under pressure. The valve's
unique design guarantees complete separation of the
liquid from the sealing mechanism and provides optimum
work conditions.
The S-020 Automatic Air Release valve is the first
of its kind in the world. It is compact and
light in weight. It has a 12 sq. mm orifice
that enables it to discharge air, gas and/or vapor
at high flow rates and it is not exposed to obstruction
by debris.
Operation
The valve is specially designed to operate with liquids
carrying solid particles such as sewage and effluent.
It provides separation of the liquid from the sealing
mechanism. The air/gas gap separation is sustained
under pressure up to 16 bar by a conical body shape
and under vibrations by a spring loaded joint.
Large dimensions automatic orifice at least 12 sq.
mm is less exposed to obstruction by debris.
Pressure
0.2 - 16 bar (3 -230 psi)
Testing pressure: 24 Atm (350 psi)
