Pressure Reducing Valve

The BERMAD Model IR-120-54-3Q-X is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower and stable preset downstream pressure. It is a Normally Closed valve that opens in response to a remote pressure drop command and shuts in the absence of that command. The BERMAD Model IR-120-54-3Q-X also serves as a Pressure Relief Valve protecting the system even when in closed position.

Features and Benefits

  • Normally Closed PRV with Relief Override Feature
    • Protects downstream and upstream systems
    • Closes upon control failure
    • Amplifies and relays weak remote command
  • 3-Way Pilot Controlled
    • Opens fully upon line pressure drop
  • Engineered Plastic Valve with Industrial Grade Design
    • Highly durable, chemical and cavitation resistant
    • No internal bolts and nuts
  • hYflow ‘Y’ Valve Body with “Look Through” Design
    • Ultra-high flow capacity – Low pressure loss
  • Unitized Flexible Super Travel (FST) Diaphragm and Guided Plug
    • Accurate and stable regulation with smooth closing
    • Prevents diaphragm erosion and distortion

Typical Applications

  • Computerized Irrigation Systems
  • Systems Subject to Varying Supply Pressure
  • Energy Saving Irrigation Systems
  • Remote and/or Elevated Plots
  • Distribution Centers
