Gate Valve Introduction
Gate valves are multi-turn valves used for isolating pipelines, allowing full open or close service. Operated by a threaded stem, the gate seals against two metal seats, often hard-faced with materials like Stellite or stainless steel, though soft seats are available for specific uses. They require less installation space compared to other shut-off valves and their slow operation reduces water hammer effects. Ideal for applications needing low pressure drop and unobstructed flow, gate valves are versatile for fluids such as water, oil, steam, gas, and slurry.
