FP430 Fire Protection Pressure Relief Valve


  • Simple design – cost effective
  • Quick cover removal – easy in-line service
  • One piece diaphragm – reliability
  • Line-pressure driven
  • Unrestricted flow path


The Bermad Model 430-UL/FM remains closed as long as the inlet pressure is lower than the setpoint. When it senses inlet pressure that is higher than the pilot setting, Model 430-UL/FM acts upon the control chamber causing the main valve to open, relieving excess pressure to either the reservoir or sump.
