Introduction to Stop Valve
A stop valve, also known as a globe valve, is a type of valve used to control the flow of a fluid (such as gas or liquid) through a pipeline. It operates by moving a disc or plug against the flow of the fluid to either stop or regulate the flow. The design of a stop valve allows for precise control of the flow rate, making it suitable for applications where accurate flow adjustment is required. Stop valves are widely used in various industries, including oil and gas, power generation, chemical processing, and water treatment.
