Pressure Reducing Valve IR-420 The BERMAD Model IR-420 Pressure Reducing Valve 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. ■ Line Pressure Driven Pressure Reducing Valve a Protects downstream systems ■ Advanced Globe Hydro-Efficient Design □ Unobstructed flow path □ Single moving part □ High flow capacity ■ Fully Supported & Balanced Diaphragm □ Requires low 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 □ Easy addition of control features [2] [3] [1] Typical Applications ■ Pressure Reducing Stations ■ Flow and Leakage Reduction ■ Cavitation Damage Protection ■ Pressure Zoning ■Downhill Supply Lines ■ System Maintenance Savings [1] BERMAD Model IR-420 reduces line pressure, protecting downhill line and consumers.
