this steam valve is used to control the flowrate of steam inject into the system. It's a steam positional valve.

It isn't clear what a "steam valve" is. Can you provide more info.
I have installed many steam systems and that is not a term I can familiar with.
Are you talking about a block valve, throttling valve, trip and throttling valve, safety valve or what?
Based on your clarification:
It may in fact be smaller than the pipe in which it is installed.
The sizing is based on the flow coefficient of the valve, the allowable pressure drop and the flow rate.
It quite common for the steam control valve to be one or two sizes smaller than the pipe in which it is installed. This is true for many control valves (either automatic or manual)

Position steam valves normally used for controlling steam flow. Different positions give different flow rates. It would be advantageous then to have it the same size as the pipe. The answer then would be yes.

If the valve is just to be used to turn the steam on and off, but not provide any flow control, then yes, it should be sized the same as the pipe.

I guess not
