🔍 Key Concepts

• safety/relief valve purpose and how it opens under pressure • what can interfere with a valve’s ability to lift and reseat properly • good piping practice when connecting rigid pipe to sensitive equipment

💭 Think About

• Think about which choice addresses how the valve itself will continue to operate correctly at its set pressure. • Ask yourself: which option, if ignored, could prevent the safety valve from lifting or cause it to leak afterward? • Consider typical shipboard practice: where do relief/safety valve discharges normally go, and what is usually more critical – routing of discharge or protection of the valve body?

✅ Before You Answer

• Verify which option is focused on the mechanical freedom and integrity of the safety valve rather than general system components. • Check standard practice for where relief valve discharge lines are led (overboard, to a safe location, not usually to the bilge). • Confirm which precaution is meant to prevent binding, distortion, or misalignment of the valve body or spindle when the piping is installed.
