Master SOPV's will always what?

• A. Open
• B. Operate
• C. Idle
• D. Close

Answer: (B)

Master SOPVs are the primary control points for starting and stopping the transfer flow. They must be operated as part of the transfer sequence to regulate whether foam solution moves through the system. Opening the valve begins flow and closing it stops flow, and throughout a typical operation you may need to operate it in different directions as procedures require. Because you actively manipulate this valve to control the system, the action described is “operate.” Choosing a word like open is too specific—you might need to open or close the valve depending on the step you’re performing. Idle would imply no action, which isn’t correct for a valve that controls transfer. Closing is also too specific and doesn’t capture the full need to perform the valve’s control as part of the process.
