IR-430-50-R

Pressure Relief/Sustaining Valve

The BERMAD Model IR-430-50-R 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 a remote pressure commands. When installed offline, the BERMAD Model IR-430-50-R relieves line pressure in excess of preset.
 

Features and Benefits

  • Hydraulic Pressure Control
    • Line pressure driven, hydraulically controlled on/off
    • Sustains supply pressure and controls system fill-up
    • Relieves excess pressure protecting pump and system
  • Advanced Globe Hydro-Efficient Design
    • Unobstructed flow path
    • Single moving part
    • High flow capacity
  • Fully Supported & Balanced Diaphragm
    • Requires low actuation pressure
