IR-130-50

Pressure Relief/Sustaining Valve

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

Features and Benefits

  • Line Pressure Driven, Hydraulically Controlled On/Off
    • 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
  • Line Emptying Prevention
  • Filter Stations
  • Energy Saving Irrigation Systems
