Why are two auxiliary lines required for regulation, and why is the steam trap installed within the control valve assembly? Wasn’t it more... earlier?

Why are two auxiliary lines required for regulation, and why is the steam trap installed within the control valve assembly? Isn’t it better in front?
The diameters of the two auxiliary pipes are different; one is likely for backup use while the other is for heating
Isn’t such a setting more reasonable in terms of process requirements?
Only 50 are for the secondary line; the other 20 are used for draining water before and after the control valve as well as on the secondary line

Because the diameter of the control valve and that of the pipeline do not match, condensation is likely to form; installing a steam trap in front of the control valve makes it easier to drain the water.
The use of two parallel lines in your case doesn’t seem very meaningful; generally, for steam or boiler water with high pressure and large diameter, in order to prevent excessive stress on subsequent pipes or equipment during startup, an additional small parallel line is used
It’s not two separate secondary lines at all; the 50-inch one is the secondary line, while the 20-inch ones are used for drainage in various sections, and they share just one drain valve.
