About Valves

A valve is a mechanical device that is used to control the volume of flow and pressure of fluids. Closing, opening, or partially opening a passage through which the fluid passes regulates this flow. Fluid can be water, gas, slurry, etc. Valves are made of different materials like cast iron, bronze, steel, aluminum, plastic, ceramic and other materials. Valves are used in areas of commercial applications, domestic and process applications, automobiles, hydraulic presses, medical equipment and many more.

Working of a Valve

In general, a valve has a plunger in the form of a rod, flap or a ball that is fixed to a shaft. The shaft and plunger assembly is housed in a casting through which the fluid passes. When the shaft is in one extreme position, the passage is open allowing the fluids to pass. At the other extreme position, the passage is blocked and the flow is stopped. The movement of the shaft and the mounted flaps or balls is calibrated. This helps precise control of liquid flow.

Types of Valves

Types of valves used in domestic and industrial applications are:
