The primary function of a gate valve is to isolate a section of the pipeline. This means that when the gate valve is fully opened, it allows for unobstructed flow of water, but when it is closed, it completely stops the flow. Gate valves are typically used in situations where a straight-line flow of fluid is desired, and they are not intended for throttling or flow regulation. They excel at providing a tight seal to prevent leakage when closed, making them ideal for maintenance activities or in emergencies, where isolating certain sections of the pipeline is necessary.

The other functions listed are performed by different types of valves or devices. For instance, controlling the flow of water is generally done by valves designed for throttling, such as globe valves or ball valves. Filtering water is the responsibility of filtration systems, not valves. Reducing water pressure typically requires a pressure regulator or reducing valve rather than a gate valve, as a gate valve is not designed to control or modify pressure in the pipeline.
