The gate valve is perhaps the most frequently used valve in piping systems. It is a general service valve that is used primarily for on-off, nonthrottling applications. When fully opened, the gate valve creates minimal obstruction to the flow. With less obstruction to the commodity’s rate of flow through the valve’s body, there is less turbulence, resulting in a minimal drop in commodity pressure. Gate valves control the commodity flowing through the pipe with a flat, vertical wedge, or gate, that slides up or down as the valve’s handwheel is turned. As the handwheel is rotated, the wedge will slide through the valve body to block or release the flow.

- The body of a gate valve holds all of the operational parts of the valve. It is connected to the system with one of the mounting options below. The mounting option should be selected based on the current system mounting features and the type and size of the media.
- The bonnet of a gate valve contains the moving parts and is attached to the valve body. The bonnet can be removed from the body in order to allow for maintenance and replacement parts.
- The trim of a gate valve contains the functioning pieces of the valve: the stem, the gate, the disc or wedge, and the seat rings.
- Gate valves are one of the most used valves in gas processing plants, chemical plants, and more where pressure remains low, but the temperature is high.
- Gate valves are installed in pipe ways as isolating valves. While operating the valve, the gate moves up or down.
- Gate valves require less maintenance and are suitable for high-pressure temperatures.
- Gate valves are widely used for all types of applications and are suitable for both above-ground and underground installation.
