Introduction to Gate Valves
A gate valve is a type of valve used to control the flow of a fluid (such as water, oil, or gas) through a pipe. It operates by raising or lowering a gate, which is a flat or wedge - shaped disc, to either allow or block the flow. Gate valves are known for their full - bore design, which means that when fully open, they offer minimal resistance to the flow of fluid, resulting in low pressure drop. This makes them suitable for applications where a straight - through flow and minimal flow restriction are required, such as in water supply systems, oil and gas pipelines, and industrial processes.
