Pressure Reducing Valve with Downstream Over-Pressure Guard IR-420-48 The BERMAD Model IR-420-48 Pressure Reducing Valve with Downstream Over-Pressure Guard is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure. The downstream over-pressure guard feature enables an immediate closing response, minimizing deviation from set point caused by a sudden drop in demand or an upstream pressure peak. Features and Benefits ■ Line Pressure Driven Pressure Reducing Valve □ Protects downstream systems ■ Hydraulic Over-Pressure Guard □ Minimizes deviation from set point ■ Advanced Globe Hydro-Efficient Design □ Unobstructed flow path □ Single moving part □ High flow capacity ■ Fully Supported & Balanced Diaphragm □ Requires low opening and actuation pressure □ Excellent low flow regulation performance □ Progressively restrains valve closing □ Prevents diaphragm distortion ■ Simple In-Line Inspection and Service Typical Applications ■ Pressure Reducing Stations ■ Systems Subject to Sudden Demand Changes ■ Lines Exposed to Upstream Pressure Peaks ■ Flow and Leakage Reduction ■ Pressure Zoning ■ Downhill Supply Lines ■ System Maintenance Savings [1] BERMAD Model IR-420-48 reduces line pressure, protecting the system even when demand suddenly drops or upstream pressure suddenly rises.
