Abstract: High-pressure gate valves, which prevent fluid flow through the tight seal between the gate and the valve seat, provide excellent sealing performance and are easy to operate and maintain, making them widely used in the oil and gas exploration industry. In offshore oil and gas exploration, high-pressure gate valves are primarily used to connect pipelines in high-pressure systems such as wellheads, well control devices, and well testing equipment. They play a critical role in controlling...

Introduction Gate valves are a fundamental component widely used in various piping systems across multiple industries. Their primary function is to control the flow of fluids by allowing either full flow or complete shutoff. Unlike other valve types designed for throttling, gate valves are generally used where fast closures are not required. They serve as on/off valves, functioning effectively when positioned fully open or fully closed. A gate valve typically consists of several critical components,...
