Decrease Non Revenue Water (NRW) by using Pressure Management Valve in Suzhou, China.

In 2018, Wujiang HuaYan Water has tested the DN100 Pressure Management Valve from AFC in order to decrease the NRW for water distribution area in XiDong Village, WuJiang, Suzhou City, China. It was a great success.

For daily water supply, the flow rate ranges between 1095 m3/day to 945 m3/day. Based on following chart, we can see the minimum flow rate per hour dropped a lot during off-peak periods.

It has been proved that pressure control has a tremendous improvement in NRW.

AFC valves are made in ductile iron which provides a long service life.
