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
