I want to switch a gas flow from line A to line B.
This gas is injected into my reactor at a point A (flow Q and a pressure P).
For maintenance reasons, a part of this reactor which contain injector A is isolated and the gas switches to the line B.
The second injector B supplies the same reactor but in another point.
I must ensure the same flow and inlet pressure (Q and P) in B.
Is it possible to make this configuration by a three-way valve which guarantees me a switching of the flow at the same pressure?
