SENSUS Gas Regulator model 496

A gas regulator is a crucial device that controls the flow of gas from a high-pressure source (such as a cylinder or pipeline) to a lower pressure application. Its primary function is to maintain a constant output pressure, regardless of fluctuations in the input pressure¹. Here’s how it works:

1. Pressure Control: Gas enters the regulator’s chamber, exerting pressure on a diaphragm. The diaphragm moves upward, controlled by a set spring. This allows a specific flow of fuel from the source to the appliance or device.

2. Adjustment: Turning the control knob adjusts the rate of flow and pressure. Clockwise increases the gas flow, while counterclockwise reduces it.

3. Atmospheric Influence: The surrounding air pressure (based on elevation above sea level) affects gas pressure. The regulator senses both upstream and downstream pressures to maintain stability².
