Process and instrumentation are inseparable; to help everyone gain a better understanding of the basics of instrumentation, we have launched the \"One Question per Day\" series – just reply to get the answers. To encourage ongoing participation from everyone! You get 3 wealth rewards just for participating! I hope everyone will participate actively, learn together, and make progress together! ! ! True or False: 16. Is the following statement correct? FO---Close the valve in case of an accident----The valve closes when there is no gas supply (gas-driven valve)—Select to open the valve with gas pressure. FC---Open the valve in case of an accident----The valve opens when there is no gas supply (gas-driven valve)—Select to close the valve with gas pressure. FL---Lock the valve in place in case of an accident----The valve is locked when there is no gas supply (gas-driven valve)—Select a valve driven by dual gas sources. The correct answer is: Wrong. FC---Close the valve in case of an accident----The valve closes when there is no gas supply (gas-driven valve)—Select to open the valve with gas pressure. FO---Open the valve in case of an accident----The valve opens when there is no gas supply (gas-driven valve)—Select to close the valve with gas pressure. FL---Lock the valve in place in case of an accident----The valve is locked when there is no gas supply (gas-driven valve)—Select a valve driven by dual gas sources

× FC---Close the valve in case of an accident----Close the valve when there is no gas supply (gas-driven valve)—Select to open the valve with gas flow. FO---Open the valve in case of an accident----Open the valve when there is no gas supply (gas-driven valve)—Select to close the valve with gas flow. FL---Lock the valve in its position in case of an accident----Lock the valve when there is no gas supply (gas-driven valve)—Select a valve driven by gas from both directions

Error. FO means start in case of accident, FC means stop in case of accident.
