Switching flow

[Biza]

I want to switch a gas flow which supplies an equipment at a point A to a flow Q and a pressure P, for maintenance reasons I have to isolate a part of this equipement and I inject the same flow Q at a second point B of the same equipment and I must ensure the same inlet pressure.
Is it possible to make this configuration by a three-way valve which guarantees me a switching of the flow at the same pressure?
or I have to use 2 valves for each line with flow or pressure regulator?

Thank you

"for maintenance reasons"... are you a student?
