Valve

Definition

A valve is a mechanical device that controls the flow of liquid, gas, or loose materials by opening, closing, or partially obstructing one or more passageways.

Purpose

Valves are essential components in plumbing, gas, and industrial systems for regulating flow, pressure, and direction of fluids and gases. They ensure safe and efficient operation of these systems.

Examples of Use

• Plumbing Systems: Using valves to control water flow in household plumbing, including faucets and shut-off valves.
• Gas Pipelines: Installing valves to regulate gas flow and pressure in distribution networks.
• Industrial Processes: Implementing valves in manufacturing to control the flow of chemicals and materials.

Related Terms

• Ball Valve: A valve with a spherical disc to control flow.
• Gate Valve: A valve that opens by lifting a barrier out of the path of the fluid.
• Check Valve: A valve that allows fluid to flow in one direction only.

Notes

Valves must be selected and maintained based on their specific application requirements, including the type of fluid, pressure, temperature, and flow rate. Regular inspection and maintenance are crucial for reliable operation.
