Which of the following procedures would insure proper seating of the valve when closing?
AI Explanation
The correct answer is B) closed, opened a half turn, and then closed again.
This procedure ensures proper seating of the valve by allowing the valve to self-align and seat properly when closed. Closing the valve all the way and then opening it slightly before re-closing allows the valve to settle into its optimal position, preventing potential leaks or improper seating that could occur from simply closing the valve tight against the stop.
The other options are incorrect because A) using a wrench to close the valve tightly may damage the valve, C) inserting a locking pin does not ensure proper seating, and D) closing the valve as tight as possible by hand does not provide the necessary controlled opening and re-closing to allow the valve to seat properly.
