Question 1 of 27070

Which of the problems listed could happen if you attempted to force open a valve 'frozen' in position by using a wrench on the hand wheel?

🔍 Key Concepts

• How force applied at the hand wheel is transmitted through the valve stem and into internal parts • Which parts of a valve are most slender or fragile under bending or torque loads • Difference between damage to sealing surfaces vs. damage to structural parts of the valve body

💭 Think About

• When you put a wrench on the hand wheel, which part of the valve actually feels the twisting force first? • Which component is most likely to deform from torsion before the heavy body or bonnet is damaged? • Is a frozen valve more likely to lose its external shape, or to have an internal moving part bent or twisted?

✅ Before You Answer

• Identify which component is the main moving, load‑carrying part between the hand wheel and the disk/plug • Compare relative strength and thickness of the stem vs. the body and bonnet • Consider whether sealing damage is a direct result of torque on the hand wheel, or a secondary consequence of another part failing
