Proportionator/Zero Governor
Proportionator / Zero Governor
Karl 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. Please contact us for assistance in sizing for your particular application.
