Valves provide several functions. Like, the valve can control the material staring in or stopping out. It also can regulating flow and pressure within the piping system. The direction of the flow also can be controlled under the pipe system. The rate of the throttling flow also can be managed. Improving safety through relieving pressure or vacuum in a piping system.

Gate valves tend to be less expensive than ball valves, but are more susceptible to corrosion. Over time, the internal stem that connects the knob to the gate becomes increasingly likely to fail. They are often used with larger pipe diameters of two inches and up. Ball valves are more effective at f
