Surge Protection Solutions for Desalination Plant Water Supply Systems

Located in the city of Hadera, one of Israel's largest and advanced desalination plants plays a key role in transforming seawater into fresh, drinkable water. From here, the desalinated water is lifted to an operative reservoir at Mekorot's Hadera Pumping Station, then pumped into the "Israel's National Carrier" pipeline, which runs from the north to

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.

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.
