Changsha Valve to Test Leakage Control Device

Changsha Valve, a subsidiary of China Valves Technology, is to test a new leakage control device, which could save up to 17,900t of water per month, at the end of June 2011.

The device will be equipped with multi-orifice regulating valve technology, advanced wireless telecommunication technology, voltage-sharing AZP algorithms and control software.

These functions will allow the user to adjust and monitor the pressure and flow of the water supply network on a real-time basis.

Changsha Valve used District Metering Area’s technology to monitor and reduce leakage levels and to achieve a leakage rate of under 5%.

China Valves CEO Jianbao Wang said the estimated total potential market value of leakage control devices is $1.8bn.

“In addition, one device could save approximately 17,900t of water per month by controlling leakage, which supports the government’s policy of energy and resource conservation,” said Wand.
