Detail Information
Carbon Steel Gate Valve, API 600, ASTM A352 LCB, 4 Inch/DN100, ANSI 1500, OS&Y, RTJ Flanged.
A gate valve is a multi-turn valve designed for isolation in pipelines, providing full open and close functionality. It operates by a threaded stem that forces the gate into two seats, blocking the flow. These seats are typically metal with hard-facing materials such as Stellite (CoCrW) or stainless steel overlay for durability, though soft seats can be used for specific services like water. Compared to other shut-off valves, gate valves require less installation space, and their multi-turn design ensures slow operation, helping to prevent water hammer. They are ideal for applications needing minimal pressure drop and unobstructed flow and are commonly used with various fluids, including water, oil, steam, gas, and slurry.
