How the Series 41 Low Pressure High Flow Regulator Works<\/h3>

The Series 41 is a manually adjustable spring operated pressure reducing regulator. The spring force is manually set using the adjustment knob. The spring acts on the top of the diaphragm assembly to open the main internal valve which allows the compressed gas supply to flow into the system and increase the system pressure. This increase in system pressure is sensed by the diaphragm. When the system pressure rises sufficiently to become equal to the force exerted by the set point spring then the main valve will close and no additional compressed gas supply will be allowed into the system. Should the system pressure rise above the desired set point provided by the spring, or if the spring set point is manually adjusted downward, then the internal exhaust valve will open to vent the excess pressure. In this manner pressure is maintained at the set point provided by the spring by adding compressed gas from the supply or by venting any excess system pressure through the exhaust port. The large sensitive diaphragm makes the Series 41 an ideal pressure regulator for low pressure applications, particularly when high flow rates are required.<\/p>
