A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll. The different types of valves include foot valve, stop valve, no-return valve, butterfly valve, diaphragm valve, pinch valve, pressure relief valve and control valve.

A key mechanical component in several devices, valves are very useful for hardware and electronics projects. They block pipes either partially or completely in order to regulate the amounts of fluids/air passing through. They can be found in any machine using liquids or gases.

Valves have many uses today, the most common being residential uses such as switching on and off and regulating pressure and water levels in dishwashers, washing machines, as also the taps in restrooms and wash basins. Valves are also used for commercial purposes such as controlling water for irrigation and industrial uses for controlling processes. Aerosol spray cans have small valves built in; additionally, they are also used in the transport industry.

There are a large variety of valves and valve configurations for a wide variety of purposes and conditions: different uses (on/off, control), different fluids (liquid or gas; combustible, toxic or corrosive), different materials (metal or nonmetal) and different pressure and temperature conditions (low, medium or high pressure applications and low-, room- or high-temperature applications).

Isolation Valves: Ball, butterfly, diaphragm, gate, pinch, piston, and plug valves. Regulation Valves: Ball, butterfly, diaphragm, globe, needle, pinch, and plug valves. Safety Relief Valves: Pressure release and vacuum relief valves. Non-Return Valves: Swing check and lift check valves.

Valves are mechanical devices that controls the flow and pressure within a system or process. They are essential components of a piping system that conveys liquids, gases, vapors, slurries etc..

A valve is a mechanism that opens and closes to control the flow of fluids. In a scientific context, fluids include both liquids and gases – any substance that can flow freely – and valves may use either. Valves control fluid flow in motors, plumbing, irrigation, pneumatic and hydraulic systems.

A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve.

The first step in finding the size of a valve is to determine the flow. coefficient (Cv) that is required for the system. Cv factor is defined as. “the number of US, gallons per minute of 60F water that will flow through. a fully open valve with a 1 psi drop across it”.

A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve.

Ball valves are perhaps the most reliable type of valve and are commonly used for main water shutoffs and for branch line shutoffs.

These parts include the valve seat, disc, glands, spacers, guides, bushings, and internal springs.

Examples of the common types are the ball valve, butterfly valve, globe valve, gate valve, plug valve, diaphragm valve, reducing valve, needle valve, check valve, and safety/relief valve. Each type of valve has been designed to meet specific needs.
