ABSTRACT:
A fuel control valve construction is provided, the construction having a housing provided with an inlet adapted to be interconnected to a fuel source and an outlet adapted to be interconnected to a burner. The housing has a main pressure regulator and a main valve operated by the main pressure regulator for controlling fuel flow from the inlet to the outlet to provide a full rated flow of fuel to the burner. The housing has a by-pass for interconnecting the inlet to the outlet to provide a fuel flow to the burner that is less than a full rated flow of fuel but is sufficient by itself to support combustion at the burner until the main valve provides the full rated flow of fuel thereto. The housing has a by-pass pressure regulator for controlling the flow of fuel through the by-pass independently of the operation of the main pressure regulator.
