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
  • Flow and Leakage Reduction
  • Pressure Zoning
  • Downhill Supply Lines
  • System Maintenance Savings
