🔍 Key Concepts

• How a spring-loaded safety valve controls set (lifting) pressure • Which part of the valve changes spring compression when adjusted • Difference between parts used for testing or gagging the valve and parts used for permanent pressure setting

💭 Think About

• Look at which labeled part is directly connected to the top of the spring and would change its compression if turned or moved. • Ask yourself: if I wanted this valve to lift at a higher pressure, which part would I adjust to squeeze the spring tighter? • Consider which labeled parts are mainly for flow (inlet/outlet), which are for manual lifting, and which are for mechanical adjustment.

✅ Before You Answer

• Identify the part that actually bears on the top of the spring and can be screwed up or down. • Eliminate any parts that are clearly inlet seat or outlet passages, since these do not set lifting pressure. • Watch out for parts used only as a cap or cover over the real adjusting mechanism; the cover itself is usually not what you readjust for set pressure.
