In the event of a power failure to the salinity panel on a flash-type evaporator, the three-way solenoid valve will __________.

🔍 Key Concepts

• Fail-safe design of control valves in potable water systems • Normal function of a salinity controller and three-way solenoid valve in a flash-type evaporator • Where high-salinity distillate should be kept from entering in the system

💭 Think About

• Ask what the salinity panel and its three-way solenoid are protecting, and what the worst thing would be if they failed in the wrong direction • Think about whether system designers want the failure mode to risk contaminating the potable water tank or to waste some distillate instead • Consider where it is safest for questionable-quality distillate to go until the problem is corrected

✅ Before You Answer

• Identify the primary safety/quality concern of the salinity panel (protecting which tank or system) • Determine whether the valve’s fail condition should send flow to a safe disposal or recirculation point, or to a tank used for human consumption • Confirm that in a power loss, solenoid valves default to a mechanical fail position chosen for safety, not convenience
