A gate valve is a type of valve that uses a gate or wedge-shaped disc to control the flow of fluid.

• Gate valves are primarily used to start or stop the flow of fluid in a pipeline.

• They have a sliding gate or disc that moves perpendicular to the flow of fluid.

• When the gate is fully lifted, the flow is unrestricted, and when it is fully closed, the flow is completely stopped.

• Gate valves are commonly used in applications w...read more

HSD density refers to the density of High-Speed Diesel fuel.
