A gate valve is designed to control the flow of liquids and gases by raising or lowering a gate inside the valve body. It provides reliable shut-off performance with minimal pressure loss when fully open, making it suitable for applications where full flow or complete isolation is required. Constructed from durable materials, gate valves are available in various sizes, pressure ratings, and connection types. They are widely used in water supply, oil and gas, chemical processing, industrial pipelines, and other fluid control systems.
