Water Air Valves |
| D-40 "Barak" Combination Air Valve |
D-060 HFNS Combination Air Valve for High Flow Non Slam |
|
This is the double orifice version of the rolling seal mechanism. Due to the relatively large "automatic" orifice, this valve has an inherent two-stage non slam closure effect. |
|
This is a double orifice dual purpose air valve with full bore orifice and two stage closing action to prevent water hammer effects if too high a velocity is generated during filling of a pipeline, or at water column return. |
| S-050 "SEGEV" Automatic Air Release Valve |
M-040 METAIR Combination Air Valve for Water Meter Protection |
|
This is a single orifice air valve which functions as a automatic valve to extract air from pressurised pipes. The orifice sealing mechanism works on a rolling seal principle (which is the original ARI patent). |
|
The presence of air in a pressurized piping system may cause both metering inaccuracies and damage to the water meter. The METAIR M-040 is used to improve metering accuracy and meter protection. |
| S-012, S-014, S-016 Automatic Air Release Valve For High-Pressure Systems |
UFR - Unmeasured Flow Reducer |
|
Lightweight, small dimensions, simple and reliable structure. The drainage outlets enables removal of excess fluids. |
|
All water flow turbine meters have difficulty measuring low flow rates. 2.5m3/h water turbine meters (those generally used in Israel) begin measuring litres per hour. |
Sewage Air Valves |
| D-020 "Saar" Combination Air Valve for Sewage |
D-023 Combination Air Valve for Sewage |
|
This double orifice air valve has solved one of the problems with air valves on sewage, i.e. Fouling up to the orifice resulting in sewage leaking to atmosphere. |
|
Responding to the demands of special conditions for sewage, ARI developed a new model of sewage air valve, keeping the unique features of the "SAAR" combination air valve together with the advantage of the spring loaded joint between the stem and the upper float and a larger kinetic orifice. |
| D-025 "Saar" Combination air Valve for Sewage |
|
|
This double orifice air valve had most of the same features as the original Saar but is manufactured in a reinforced Nylon, 316 Stainless Steel or Ductile iron body and is much more compact for installations with limited space. |
