IR-130-55

Pressure Relief/Sustaining Valve

The BERMAD Pressure Relief/Sustaining Valve with Solenoid Control is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure regardless of fluctuating flow or varying downstream pressure. It either opens or shuts in response to an electric signal. When installed offline, the BERMAD Model IR-130-50 relieves line pressure in excess of preset pressure.
 

Features and Benefits

  • Line Pressure Driven, Electrically Controlled On/Off
    • Line pressure driven
    • Sustains upstream line pressure controlling system fill-up
    • Relieves excess pressure protecting pump & system
  • Engineered Plastic Valve with Industrial Grade Design
    • Adaptable on-site to a wide range of end connection sizes and types
    • Articulated flange connections eliminate mechanical and hydraulic stresses
    • Highly durable, chemical and cavitation resistant
  • 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 opening and actuation pressure
    • Prevents diaphragm erosion and distortion
  • Simple In-Line Inspection and Service
     

Typical Applications

  • Computerized Irrigation Systems
  • Pressure Zone Prioritizing
  • Line Fill-up Control
