🔍 Key Concepts

• Thermostatic control valves with a remote bulb (like part J in the illustration) • The difference between simple flow control and automatic temperature control • How a valve’s fail position (opens or closes as temperature rises) affects whether it is used for heating or cooling

💭 Think About

• Look closely at the sensing bulb and bellows: as the sensed temperature rises, does the mechanism tend to open or close the main valve? How would that behavior match a heating vs a cooling duty? • Which of the listed services absolutely requires automatic, proportional temperature control rather than just simple throttling of steam flow? • For a fluid being heated vs a fluid being cooled, which service is usually arranged so that loss of control power or bulb failure does not lead to overheating or damage?

✅ Before You Answer

• Identify that part J is a remote temperature-sensing bulb and that the valve is therefore a self‑contained temperature controller, not just a hand‑operated throttling valve. • Determine whether the valve is designed to control the heating medium (steam) or the cooling medium (water, condensate, etc.) based on how it moves with rising temperature. • Match that behavior to the answer choice that describes automatic temperature control of a process stream, not simple on/off steam flow for a turbine or ejector.
