🔍 Key Concepts

• Difference between thermostatic, float, and orifice type steam traps • How temperature changes affect certain materials or fluids inside a trap • What process actually causes a thermostatic element to open or close in response to steam vs. condensate

💭 Think About

• Which choice directly involves a change with temperature rather than level or flow? • For each option, ask: does this describe something that would open or close the trap as the temperature of the condensate changes? • Eliminate any answers that mainly depend on liquid level or flow rate instead of temperature-responsive action

✅ Before You Answer

• Be clear on what thermostatic means (linked to temperature, not pressure or flow). • Identify which option describes a mechanism that changes size or position when heated/cooled. • Confirm that the mechanism would reasonably distinguish cooler condensate from hotter steam.
