In the boxed area of the diagram, what do the dashed circles represent? Why are two valves connected in series to connect to the instrument, and what is their function? Thank you all!

Inside the dashed line is a three-valve assembly; the valves on both sides are high and low pressure stop valves, while the valve in the middle is a balance valve.
