Description
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.
