WebJan 29, 2003 · The pressure regulating valve works by a force being applied to the spring which is the desired set point, this pushes down on the diaphragm holding the valve in an open position allowing flow through the valve. Somewhere downstream a pressure reading is taken and transfered to the underside of the diaphragm. If the force downstream is … WebPressure reducing valves (PRVs) throttle (ie. restrict) flow to prevent the downstream pressure or hydraulic grade from exceeding a user-defined value. PRV Effects on the System The upstream hydraulic grade and pressure increase. The downstream hydraulic grade and pressure decrease. Practical Applications
WebJun 27, 2024 · A pressure reducing valve is a valve which takes a high inlet pressure and reduces it to a lower outlet pressure. When it does this under both flow and no-flow conditions, the type of control is known as ‘drop tight’. Reliance’s pressure reducing valves use a balanced spring and diaphragm to control the downstream pressure. WebSimilar to a tire gauge, a pressure reducing valve is needed to protect your plumbing systems from various kinds of risks like busted appliances, floods, and leaks. Because a …
