When the system is under pressure, the air valve
can discharge a small amount of air and gas effectively; When the system is emptied, the air valve
sucks in a lot of air. Each adopts the advanced design in line with gas dynamics, with fast inlet and exhaust port, automatic micro exhaust port and waterproof hammer device. The valve avoids air and gas accumulation, water hammer and pressure fluctuation, and has a good sealing performance at low pressure. There are typical application cases in every working condition, such as sewage and wastewater system pump station - discharge air, avoid forming negative pressure and prevent water hammer.
Sewage and wastewater system pipes - prevent air and gas from accumulating at the high points of the pipes, the turning points of the slopes and the road/river intersections, eliminate negative pressure, prevent the formation of negative pressure where water column separation is easy to occur in the system, and prevent pressure fluctuations and water hammer; Municipal and industrial wastewater treatment plants - prevent air and gas accumulation and negative pressure. Therefore, under any working condition, using the exhaust valve of ZhengFeng, we have the corresponding configuration strategy to provide to the customers of each using unit.
