Q

Expansion valve maintenance should include which of the following procedures?

🔍 Key Concepts

• Thermostatic expansion valve (TXV) purpose in a refrigeration system • Importance of thermal bulb placement and contact on the suction line • Role of strainers/filters in protecting the valve from debris

💭 Think About

• Think about what could cause an expansion valve to mis-sense temperature or pressure and therefore feed refrigerant incorrectly. • Consider what kinds of simple, routine checks a watchstander or engineer can reasonably perform without disassembling the valve. • Ask yourself: if dirt or poor bulb contact affects valve operation, which maintenance tasks would directly help prevent those problems?

✅ Before You Answer

• Verify which options relate to correct sensing of suction line temperature by the thermal bulb. • Check which options help maintain unrestricted refrigerant flow and protect the valve from clogging. • Confirm whether any of the listed actions would be unnecessary or unsafe as normal maintenance on a TXV.
