IR-430-55-R
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-430-55-R relieves line pressure in excess of preset pressure.

Features and Benefits

Hydraulic Pressure Control with Solenoid Control

  • Line pressure driven
  • Sustains upstream line pressure controlling system fill-up
  • Relieves excess pressure protecting pump and system
  • Electrically controlled On/Off

Advanced Globe Hydro-Efficient Design

  • Unobstructed flow path
  • Single moving part
  • High flow capacity

Fully Supported & Balanced Diaphragm

  • Requires low opening and actuation pressure
  • Excellent low flow regulation performance
  • Progressively restrains valve closing
  • Prevents diaphragm distortion

User-Friendly Design

  • Easy pressure setting
  • Simple in-line inspection and service

Typical Applications

  • Computerized Irrigation Systems
  • Remote and/or Elevated Plots
  • Pressure Zone Prioritizing
  • Line Fill-Up Control
  • Line Emptying Prevention
  • Irrigation Machines
  • Low Supplied Pressure Irrigation Systems
