Question 1303 Deck General

The correct answer is C) From below the seat. In a globe valve installed in a normally open position, the proper direction of flow is from below the seat. This is because the pressure from the flow pushes the valve disc against the seat, keeping the valve open. If the flow were to come from above the seat, the pressure would push the valve disc down, closing the valve, which is the opposite of the desired normally open configuration. The other options are incorrect because: A) The direction of flow is not dependent on the seat configuration, but rather the desired valve position. B) The direction of flow is important to maintain the valve in the normally open state. D) Flow from above the seat would close the valve, which is not the proper configuration for a normally open valve.
