What is the purpose of thermostatic control valves in engine cooling water systems?
Direct Answer
Option C: Maintain constant engine cooling water temperature by modulating bypass flow to heat exchanger
Thermostatic control valves regulate cooling water circuits by utilizing wax-element actuators to proportion flow between the engine jacket and central heat exchangers. This maintains optimal operating temperatures regardless of sea water temperature changes or engine load variations.
