Best 10 Stop Valve Factory in China

Introduction to Stop Valve

A stop valve, also known as a globe valve, is a type of valve used to stop, start, and regulate the flow of fluid within a pipeline. It consists of a movable disk-type element and a stationary ring seat in a generally spherical body. The operation of a stop valve is relatively straightforward: by turning the valve stem, the disk moves up or down, creating a variable space between the disk and the seat, which controls the flow rate of the fluid. Stop valves are widely used in various industries such as oil and gas, power generation, chemical processing, and refrigeration due to their excellent shut - off capabilities and precise flow control.
