A three-way solenoid operated dump valve installed on a flash-type evaporator unit, will divert impure distillate to the bilge __________.

🔍 Key Concepts

• Flash-type evaporator operation – how distillate is produced and monitored in multiple stages • Salinity cell / salinity panel function – what the selector switch actually does • Three-way solenoid dump valve logic – what signal makes it shift to dump impure distillate

💭 Think About

• Think about what actually TELLS the three-way solenoid valve to move: is it flow, salinity, power loss, or selector position? • Ask yourself: if the salinity is high in any monitored stream, would you ever want impure distillate to be able to reach the freshwater tanks? • Consider whether safety of potable water depends on one particular stage being selected, or on the salinity signal itself.

✅ Before You Answer

• Identify what the cell selector switch really controls (measurement point vs. valve command). • Clarify whether loss of power to the salinity panel causes the valve to fail to ‘make’ fresh water or to fail-safe to dumping it. • Decide if the dump action should depend on a specific stage only, or protect the system no matter which stage is being monitored.

Question 1 of 27070

A three-way solenoid operated dump valve installed on a flash-type evaporator unit, will divert impure distillate to the bilge __________.

only if the cell selector switch is positioned to monitor the first stage distillate outlet

only if the cell selector switch is positioned to monitor the final stage distillate outlet

regardless of the cell selector switch position

only if power to the salinity panel is interrupted
