Gate valves are shut off valves, used to permit or prevent liquids from going through. They are controlled by a wheel at the top of the device. They're often used in the petroleum industry since they can cut through thick liquids. Because they open and close slowly they prevent water hammer, which makes them useful for plumbing systems. Our gate valves are made of brass, stainless steel, and non-metallic PVC. Our gate valves are available in sizes ¼” to 4”.
