Gate Valve
A Gate Valve is a common type of shut-off valve used in plumbing systems that controls water flow by raising or lowering a gate-like piece inside the valve. Think of it like a sliding door that moves up and down to let water through or stop it completely. Plumbers work with these valves regularly when installing or repairing water supply systems in homes and buildings. They're different from other valves (like ball valves or globe valves) because of their specific design and use cases. You might see them called "sluice valves" or "isolation valves" in some job descriptions.
