Question 1031 Deck Safety
70% to passWhat is the proper direction of flow through a globe valve when the valve is installed to be in a normally open position?
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 when the valve is open, the flow comes up from below the seat and lifts the disc off the seat, allowing the fluid to pass through. This direction of flow provides the least resistance and ensures efficient operation of the valve. The other options are incorrect: A) Direction is unimportant - The direction of flow through a globe valve does matter and should be from below the seat. B) From above the seat - This would go against the typical design and operation of a globe valve in a normally open position. D) Depends on seat configuration - While the seat configuration can affect the flow direction, in a standard globe valve installation, the flow should be from below the seat.
