Question 1 of 27070

Safety valve gags should only be installed hand tight in order to prevent __________.

🔍 Key Concepts

• Function of a safety valve gag during testing or maintenance • How excessive tightening could affect internal parts of a spring-loaded safety valve • Which component inside the valve is most at risk when external force is applied to the gag

💭 Think About

• When you tighten the gag, what part of the safety valve actually feels that extra force? Think about the load path from the gag to the internal parts. • Which of the choices describes damage that would most directly affect how accurately the valve lifts at the set pressure? • If the gag is only hand-tight, which potential type of damage is being limited or avoided compared to using a wrench or bar?

✅ Before You Answer

• Review how a spring-loaded safety valve is constructed: disk, seat, spindle (stem), and spring. • Consider whether the gag acts primarily against the spring, the stem, or the body when tightened. • Ask: which listed failure mode would most likely change the calibration or alignment of the valve under excessive gag force?
