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)
