S-012, S-014, S-016 Automatic Air Release Valve For High-Pressure Systems
 Lightweight, small dimensions, simple and reliable structure. The drainage outlets enables removal of excess fluids.
Standard metal body - baked polyester coating.
Automatic component
ARI patent, Rolling Seal Mechanism:
- Dramatically reduces the possibility of obstruction by debris.
- Discharges high air flow rates upto 786 m3/h.
- One size orifice for a wide pressure range (up to 64 BAR).
- Self cleaning mechanism.
All operating parts are made of specially selected corrosion resistant materials.
Working pressure range: 0.2-100 BAR (3-1400 psi).
Available in 3/4" (20mm), 1" (25mm), male threaded BSPT/NPT.
Description S-014
The S-014, S-016 series automatic air release valve releases accumulated air from the system while it is under pressure. The presence of air in a water system can reduce the effective cross sectional flow area resulting in increased pressure loss and deceased flow. Unwanted air may also cause water hammer and metering inaccuracies, while hastening corrosion.
Applications
- On high-pressure pumps.
- On high-pressure delivery pipelines
Operation
The automatic air release valve releases entrapped air from
pressurized systems.
Pockets of accumulated air may cause the following destructive
phenomena:
- Impediment of effective flow and hydraulic conductivity of the
system along with a throttling effect as would a partially closed
valve. In extreme cases this will cause complete flow stoppage.
- Accelerate cavitation damages.
- High- pressure surges.
- Accelerate corrosion of metal parts.
- Danger of a high-energy burst of compressed air.
- Inaccuracies in flow metering.
The valve functions while the system is under pressure, according to the following stages:
- Entrapped air, which accumulates at peaks along the system (where combination air valves should be installed), rises to the top
of the valve, which in turn displaces the liquid in the valve’s body.
- The float descends, unsealing the rolling seal. The automatic air release orifice opens and the accumulated air is released.
- Liquid penetrates into the valve and the float rises, pushing the rolling seal back to its sealing position.
Note: Automatic air release valves are designed to release air as it accumulates at peaks in pressurized systems. They are not normally recommended for vacuum protection or for discharging large volumes of air, because of their inherently small orifices. For this purpose, air & vacuum valves are recommended as they have much larger orifices. However, air release valves will permit air to re-enter the system under vacuum conditions. If this is not desirable, specify the oneway out check valve.
Valve Selection
- D-014 (40 bar), D-016 (64 bar) are available in 3/4”, 1”, male threaded BSP and NPT connections / flanged.
- Standard metal body - baked FBE coating according to the international standard DIN 30677-2.
- Other coatings are available upon request.
- For best suitability, it is recommended to send the fluid chemical properties along with the valve request.
Description of S-015
