🔍 Key Concepts

• Packed valves and how the packing gland functions to prevent leakage • Manufacturer’s recommended procedure for operating compressor service and line isolation valves • Safety concerns when working with refrigerant under pressure and very low temperatures

💭 Think About

• Which choice best matches the normal, routine way you would operate a valve every time, rather than something you would only do in special circumstances? • Which option could actually increase the risk of leaks or damage if done unnecessarily or incorrectly? • Think about what sudden movements or changes in a refrigeration system can cause, especially when very cold refrigerant is involved.

✅ Before You Answer

• Identify what the packing gland/packing is for on a packed valve and when it should or should not be adjusted • Consider whether you would realistically remove parts (like caps or gaskets) every time you move a valve in normal operation • Ask whether any step could introduce leak paths or mechanical stress instead of preventing them
