Advanced Surge Protection Solutions for Three Lakes Ecological Restoration Project, China
Located in the heart of Yunnan Province in southwestern China, the city of Yuxi is an industrial and ecological hub surrounded by three vital freshwater lakes: Fuxian, Xingyun, and Qilu.
In recent years, these lakes have suffered from declining water levels and increasing pollution, threatening both the environment and the communities that rely on

How Does a Pressure Reducing Valve (PRV) Work?
Function of a Pressure Reducing Valve
Designed to withstand even the toughest environments, the pressure reducing valve (or PRV) is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure—regardless of the fluctuating demand or the varying upstream force. Essentially, the valve maintains a steady state of pressure downstream, heedless of flow.

BERMAD’s 700 SIGMA Valve with Superior Cavitation Resistance Allows the Supply of Water in Extreme Working Conditions
Cavitation, which can damage delivery networks, is a given in all water supply systems. However, it is a particular concern in Australia where water supplies are already limited. In systems with inadequate pressure controls, cavitation can lead to significant damage, including pipe bursts, and ultimately a pipe burst if pressure is not properly controlled.
