Solution
Concept
Sluice (gate) valve
Step-by-step solution
1. A sluice (gate) valve is provided at street corners and at the junctions of pipes to isolate a section for repairs and regulate flow. 2. A check valve allows flow in one direction only; a safety valve relieves pressure; a scour valve is at the low points to drain the pipe.
Explanation
Sluice valves are installed at street corners and junctions so that any branch can be shut off without disturbing the rest of the distribution network.
Shortcut
Junction / street corner → sluice valve.
Common mistake
Choosing check valve because it controls direction.
Correct answer: B) Sluice valve
