🔍 Key Concepts

• Multi-element feedwater regulator function in a boiler system • What happens when pneumatic control signal is lost • Difference between automatic control and manual (local/remote) control of a valve

💭 Think About

• In a multi-element feedwater control system, what elements/signals are normally used to position the feedwater valve? • If all pneumatic control to the regulator fails, which option would still allow the operator to position the valve safely? • Which choice represents a backup method that does NOT depend on the failed pneumatic controller?

✅ Before You Answer

• Identify which options are automatic regulators that need a proper control signal to function • Identify which option(s) would let you operate the feedwater valve even if the control air/pneumatics are lost • Think about what typical boiler procedures require operators to do when automatic feedwater control systems fail — which choice best matches that action?
