🔍 Key Concepts

• Quarter-turn valves vs multi-turn valves in marine piping systems • How the disc or gate moves inside different valve types (linear vs rotary motion) • Typical uses of butterfly, gate, globe, and check valves on board ships

💭 Think About

• Think about which valve types need several turns of the handwheel to go from fully open to fully closed, and which ones move with just a quarter turn • Visualize the internal mechanism: which designs rotate a disc or plate 90°, and which move a stem up and down? • Consider which valve can be quickly shut in an emergency with just a short handle movement

✅ Before You Answer

• Identify which valve uses a rotating disc or plate operated by a lever or short handle • Eliminate any valve that has a rising stem that must travel up and down several turns • Remember that a check valve is usually automatic and does not normally have a handle to be turned
