Gate Valve Meaning Unlocked
In plumbing, one of the most important elements you need to understand is the gate valve. The gate valve, sometimes called a sluice valve, is the rectangular or round-shaped wedge that helps stop the path of fluid. It is considered a shutoff valve used mostly in industrial or commercial applications. Gate valves are used most often when you want to regulate flow or offer only minimum restriction of fluid flow. Most gate valves are used for regulating flow and are designed for this purpose, but some can be used for either preventing flow of fluid, or allowing the flow of fluid.
Gate Valves – The Floodgates in Plumbing
Gate valves can cut through different types of liquids, so they are used frequently in the petroleum industry, where thick fluids are prevalent. For extremely thick fluids, a knife valve is used, which is a stronger type of gate valve. When gate valves are designed, they can be opened completely or closed. If they are in the open position, there are no obstruction in the path of the fluid flowing, so no friction is lost.
Gate valves might have a non-rising or rising stem, which offer indication of the position of the valve in a visual way. With non-rising stems, they have a pointer threaded into the top part of the stem to show the valve position and whether or not the flow is going up or down, depending on where the stem is location.
