A valve is a mechanical device which regulate either the flow or the pressure of the fluid. Its function can be stopping or starting the flow, controlling flow rate, diverting flow, preventing back flow, controlling pressure, or relieving pressure. Basically, the valve is an assembly of a body with connection to the pipe and some elements with a sealing functionality that are operated by an actuator. The valve can be also complemented whit several devices such as positioners, transductors, pressure regulators. | A valve is a mechanical device which regulate either the flow or the pressure of the fluid.

The modern history of the valve industry starts with the Industrial Revolution. At 1705 Thomas Newcomen invented the first steam machine. It needed valves able to keep and regulate the steam at high pressure. As new inventors as James Watt created new machines, they also improve the design of the valves. But it was until many years later when the production of valves was at great scale, independently of particular projects. | The modern history of the valve industry starts with the Industrial Revolution.
