Pressure Sustaining Valve IR-130-55-X

The BERMAD Model IR-130-55-X is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting. It either opens or shuts in response to an electric signal.

Product Features & Benefits
  • Line Pressure Driven, Electrically Controlled On/Off

-Prioritizes pressure zones & controls system fill-up

-Sustains upstream line pressure

-Opens fully upon line pressure rise

  • 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

-Requires low actuation pressure

-Prevents diaphragm erosion and distortion

  • Simple In-Line Inspection and Service
