An excess pressure valve is used to control the upstream pressure (p1) to an adjusted set point. The design of an excess pressure regulator valve is to open when the upstream pressure rises above the set value.
These valves are self-operated in that the upstream pressure being controlled is tapped upstream of the valve and transmitted via a control line to the operating diaphragm of the Type 2406 where it is converted into a positioning force.
