SPECIFICATION GATE VALVE APPLICATION
Gate Valves are general service valves that can be made in a broad spectrum of sizes using a variety of materials. Gate valves are primarily used to turn on or shut the flow as opposed to regulating flow and are characterized by a traveling wedge, which is moved with the operation of the stem nut. The wedge travels perpendicular to the direction of the flow. Gate valves usually have a minimum pressure drop when fully opened, provide tight shut-off when fully closed, and remain relatively free of contamination build up.
