Where should I put this valve?
Where should I put this valve?
(OP)
I'm trying to put a 3-way valve somewhere.
1. The current valve is positioned like an upside down T. Normal operation has water coming vertically down and to the right side. Blowdown mode has water coming from the left side to the right side.
2. Another engineer conceptualized it differently. He saw it as a T on the side. Normal operation has water coming down vertically and straight down. Blowdown mode has water coming from the side and down.
Is one design better than the other? I can only think of the following reasons:
1. pressure losses are higher in the first case, and doing this for normal operation isn't as energy efficient.
2. stronger forces acting on the valve due to the 90o bend wears down the valve quicker (potential leak?)

RE: Where should I put this valve?
If it is doable, then you would want the most common flow path to be connected to the two branches for the resons you stated.

AgSilver, I think normal flow should go straight.
1: You are right;
2: I think this is neglectable.

Still, I have a feeling that losses are higher in the case where the elbow is built into the valve compared to the case with a straight-thru valve and an elbow after.
