Which term is the last fuel shutoff valve before the flame effect burner?

• A. Effect Valve
• B. Accumulator charge valve
• C. Safety shutoff valve
• D. Flame effect plan

Answer: (A)

In gas flame effects, each burner is fed through its own valve that directly meters fuel to that burner. The last valve in line before the flame is produced is the effect valve. It is the control you use to start or stop fuel flow to that specific burner, sitting downstream of the main safety shutoff. The safety shutoff isolates the entire gas supply; it isn’t the last valve for an individual burner. The accumulator charge valve serves a different purpose related to gas pressure storage rather than direct burner control. The flame effect plan is not a valve at all. So the term that corresponds to the last fuel shutoff valve before the burner is the effect valve.
