A pressure-reducing valve (PRV) in a water distribution system automatically reduces and maintains a consistent downstream water pressure, regardless of fluctuations in the upstream water pressure. The function of a PRV is to protect plumbing fixtures and appliances from excessive water pressure, which can damage them and lead to leaks. It also helps to conserve water by preventing excessive flow rates. Proper sizing of a PRV is crucial for its effective operation. The PRV must be sized to handle the maximum flow rate expected in t....
