IR-420-48

Pressure Reducing Valve

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
