Gate valve: A gate valve is one of

A gate valve is one of the most widely used isolation valves in industrial and plumbing systems, designed to control fluid flow by lifting or lowering a gate (wedge) inside the body. Unlike valves meant for throttling, gate valves are built for reliable on/off service, offering a full, unobstructed bore that minimizes pressure drop when fully open. Their simple yet durable design makes them indispensable in industries such as water supply, wastewater treatment, oil and gas, chemical ... Learn about the different types of gate valves, their construction, applications, and advantages. Compare solid, flexible, and split wedge disks, and screwed, bolted, welded, and pressure-seal bonnets. A gate valve is the most common valve for water supply systems. It represents a linear-motion isolation valve and has a function to stop or allow the flow. Gate valves got their name from the closure element sliding into the flow stream to provide shutoff and, therefore, acting like a gate . Gate valves are used to isolate specific areas of the water supply network during maintenance, repair works, new installations, as well as to reroute water flow throughout the pipeline. A gate valve is typically used in industrial settings to completely restrict flow, or to fully allow flow when it is in the open position. It achieves this by lowering or raising its obturator from the seating surface. As a result, it usually occupies more space than most types of valves and is not ideal for flow regulation.
