41-73 - Pressure Regulator (Excess Pressure)
Set Point Range: 0.75 to 400psi (0.05 to 28bar)
Size: 1/2" to 4"
ANSI Class: 125 to 300
Temperature Range: 15 to 660oF (-10 to 350oC)
The Type 41-73 self-operated universal excess pressure regulator is a standard size regulator (1/2" - 4") designed to work with in all general industrial applications. 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 41-73 where it is converted into a positioning force.
