Air & Vacuum Valves A.R.I by Aquestia

Water, Air Valves: combination air valves, kinetic air/vacuum valves and automatic air releases valve for water supply and waste-water.

AIR VALVES
A.R.I. by Aquestia air valves in pipeline systems serve two primary functions. The first is the release of accumulated air that comes out of solution within a pressurized pipeline. This air will result in bubble formation, which will gather at localized high points along the pipeline profile. This air accumulation will occur when the bubble’s buoyancy is greater than the energy to convey the bubble with the liquid. The A.R.I. air valve used to release this free air is known as an air release valve.

The second function of an air valve is to admit air into the system when the internal pressure of the pipeline drops below atmospheric pressures. By admitting air into the pipeline as the internal vacuum condition develops, the magnitude of the vacuum pressure can be reduced and as a result help prevent the pipeline from experiencing excessive deflection and/or collapse as well as help prevent the formation of a full vacuum condition in which vapor cavities may form from the fluid vaporizing. The A.R.I. air valve used in this situation is an A.R.I. air & vacuum valve. The A.R.I. air & vacuum valve is also used to discharge large volumes of air from the pipeline system when the pipeline is initially filled and after water column separation.

A.R.I. air valves can contribute to the improvement of the efficiency of the water system.

The THERMO-PROTECTION is used to isolate the air  valve and the liquid inside the air valve against different temperature levels between the pipeline and the surrounding atmosphere.If the THERMO-PROTECTION is used as an "anti-freeze-device" the input of thermal energy into the air valve by liquid-exchange between pipeline and air valve is compulsory.Only by a sufficient liquid exchange an anti-freeze protection is guaranteed at low temperatures (well approved down to – 20°C [-4°F].

Material specification:

At water column separation, drainage, pipe burst, sudden closure
of the isolating valve, pump trip, etc., the check valve and air valve
open, allowing large volumes of air into the system. When the
water column returns, air is discharged through the small orifices
(one orifice - 1½" model), at a rate determined by the orifice
opening setting (set manually by the user). This way, air discharge
is controlled, greatly reducing the effects of slam.
