The fresh water cooling system self-contained, internally-sensing thermostatic temperature control valves fitted on the main engines of your anchor-handling supply vessel are configured as shown in the illustration. If the valve sleeve (item #4) as controlled by the thermostatic sensing element (item #7) is in the position as shown in the drawing, what statement is true? Illustration MO-0079

Question

Accepted Answer

As shown, the actual engine fresh water outlet temperature must be below the temperature set point of the valve, thus diverting 100% of the water flow in bypass of the fresh water cooler.

Answer

As shown, the actual engine fresh water outlet temperature must be at the temperature set point of the valve, thus sending a portion of the water flow through the fresh water cooler and the remainder in bypass of the cooler.

Answer

As shown, the actual engine fresh water outlet temperature must be above the temperature set point of the valve, thus sending 100% of the water flow through the fresh water cooler.

Answer

As shown, it is not possible to determine what the relationship is between the actual engine fresh water outlet temperature and the temperature set point of the valve, and as such it is not possible to determine the flow pattern.
