Pressure Reducing Valve with solenid control IR-420-55 The BERMAD Model IR-420-55 Pressure Reducing Valve with Solenoid Control 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 BERMAD Model IR-420-55 opens and shuts in response to an electric signal. Features and Benefits ■ Line Pressure Driven PRV, Electrically Controlled On/Off □ Protects downstream systems □ Wide range of pressures and voltages □ Normally Open, Normally Closed or Last Position ■ 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 ■ User Friendly Design □ Easy pressure setting □ Simple in-line inspection and service Typical Applications ■ Pressure Reducing Stations ■ Flow and Leakage Reduction ■ Cavitation Damage Protection ■ Source and "On Duty” Valves Management ■ Pressure Zone Isolation ■ Downhill Supply Lines ■ System Maintenance Savings [1] BERMAD Model IR-420-55 opens in respond to an electric signal establishing reduces pressure zone.
