Air Release Valves ARSX/ARSH Series
This type of air release valve is adopted to expel 2VOL% deliquescent air in water supply system, and is suitable to be installed at high building, pipeline in plant, small scale pump station and fire-fighting system to protect or improve efficiency of water transportation and save energy.
Specification:
Valve size: DN15-DN25
Pressure rating: PN10 PN16 PN25
Combination Air Release Valves CARX
Application Purpose:
Improve pump efficiency, improve pipe transportation efficiency; Protect pipe from damage of negative pressure
Operation Principle:
When water starts to fill the pipeline, poppet of the valve stays at open position, and expels out a great deal of air.
After all air is expelled out, water enters into the valve, ball is floated up, which drives the poppet to close position, the valve stops expelling air out.
During normal water transportation, some deliquescent air accumulates in valve and reaches certain degree, water level inside of the valve starts to lower, and the ball lowers to expel the accumulated air consequently.
When pump stops, vacuum will happen in the pipeline, then the poppet will drop quickly to absorb air to ensure safety of the pipeline.
Combination Air Release Valves SCAR Series
Brief Introduction:
Sewage used combination air release valves have the same principle as air release valves for clean water, but only differ in appearance, with the bodies being considerably longer in height. The elongated bodies serve to minimize the problem of clogging by permitting the use of a long float stem, which creates an air pocket to prevent the sewage from fouling up the mechanism.
Specification:
Pressure rating: PN10
Valve size: DN50-200mm
