arvx micro exhaust valve under normal circumstances, the water contains about 2vol% dissolved air, the main water delivery process, the air continuously released from the water, gathered in the pipeline at the high point, the formation of air bags (air pocket) as water transfer becomes more difficult, the system's ability to deliver water can therefore be reduced by about 5-15%. the main function of this micro exhaust valve is to eliminate the 2vol% of dissolved air and is suitable for installation in high-rise buildings and pipelines in the plant area. the small pump station is used to protect or improve the system's water delivery efficiency and save energy.
single lever (simple lever type) micro exhaust valve, an oval-shaped valve body, all internal components, including float, lever, bar, valve seat, etc. are 304s.s stainless steel, the internal standard exhaust aperture 1/16 ", suitable for pn16 working pressure ring zhang.
