How does a regulator work?
The below information is taken from the Elgas website which gives an easy to understand explanation.
Regulators have a diaphragm, which is a flexible rubber disc that responds to pressure changes and functions to regulate the flow of gas to the proper pressure. The diaphragm works in combination with springs and other parts within the regulator. It also works in conjunction with the regulator vent which allows the diaphragm to move freely. If the vent is obstructed, the diaphragm will not operate properly. The vent should remain free of dirt and debris to ensure the regulator operates correctly.
