Question 1 of 27070

Valves used in diesel engine fuel oil pressure piping are to be __________.

🔍 Key Concepts

• Fuel oil pressure piping safety on diesel engines (fire risk, leakage control) • Types of valve designs commonly used in high‑pressure fuel systems • Relevant machinery regulations in 46 CFR – Marine Engineering for fuel oil piping and valves

💭 Think About

• Which type of valve construction best minimizes leakage and fire risk in high‑pressure fuel oil lines on a diesel engine? • Look at each choice and ask: is this a general design requirement for all such valves, or is it a special feature/interlock used only in some systems? • Think about which valve type is normally used where you want positive shutoff and minimal flow restriction, rather than throttling or frequent adjustment.

✅ Before You Answer

• Verify which option describes a basic, always‑required characteristic of valves in diesel engine fuel oil pressure piping, not an optional safety add‑on. • Check which valve types are typically avoided in high‑pressure fuel service due to throttling, erosion, or complex packing adjustments under pressure. • Confirm against machinery rules (46 CFR marine engineering) which valve types or constructions are explicitly permitted or required for fuel oil pressure piping.
