Pressure Reducing Valves [PRVs] are commonly used in multistorey buildings for cold water and water potable supply and for cold water for fire services. They generally fall into two design categories: Direct Acting and Pilot Operated PRVs. Each of these valves has particular characteristics that are ideally suited to specific applications. A better understanding of these design features will ensure that you select the optimum PRV for individual applications or overall pipeline systems.
