Hi
What type of reducer should we use before and after in-line control valve in liquid systems? (Eccentric top flat, bottom flat or concentric),and Why? Could u mind address a reference for this issue?

I would suggest, if you took a survey of all the Control Valve manifolds in all the world you would find that Concentric reducers are the only ones used.
prognosis: Lead or Lag

It's more about your piping layout and where your vents and drains are than anything else and only you know that.
As pennpiper says, the majority are probably concentric because it looks good and there is no disruption to flow. Either that or bottom flat a few pipe diameters away from the valve so you don't get any strange vortices or anything.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way

Learn from the mistakes of others. You don't have time to make them all yourself.
