Gate Valve

Gate valves have a flat disc called gate that travels perpendicular to the flow stream. They are operated by manual hand wheel for small sizes, gear operated hand wheels for larger sizes.The API600 gate valves usually adopt flexible wedge gate structure.Solid wedge is optional.Gate valves are widely used in onshore and offshore oil and gas production, refining, petrochemical, chemical processing, power generation, and water treatment plants, among other industries.

Diameter through the gate valve is same as the diameter of the pipe. When gate is fully open, it gets completely out of flow stream, hence there is minimum pressure drop in this type of valve.Gate valves don’t have the flow control function.It’s only be used as on-off purpose.
