Gate valves have an extended use in the petrochemical industry due to the fact that they can work with metal-metal sealing.

They are used in clean flows.

When the valve is fully opened, the free valve area coincides with area of the pipe, therefore the head lose of the valve is small.

This valve is not recommended to regulate or throttling service since the closure member could be eroded. Partially opened the valve can vibrate.

Opening and closing operations are slow. Due to the high friction wear their use is not recommend their use in often required openings.

This valve requires big actuators which have difficult automation. They are not easy to repair on site.
