Abstract
A solenoid operated fluid pressure regulating valve includes a valve responsive to outlet pressure to control the rate of fluid flow to a burner. The valve is biased to a first position to effect a low fire fluid flow rate and to a second position to effect a high fire fluid flow rate. The first and second positions are independently adjustable so as to enable independent field adjustment of the low and high fire fluid flow rates. Lower and upper limits to such field adjustments are established in the assembly of the valve.
