Proportionator/Zero Governor and Regulators
Dungs FRG series regulators automatically adjust gas flow based on air flow. When the diaphragm is under positive pressure as it is when used with a nozzle-mix burner, it is called a proportionator. When used under negative pressure as in the case of a proportional mixer, it is called a zero governor.
Pressure switches open and close electric circuits to verify safe gas and air pressure. We offer pipe mount and valve body mount versions.
