What is the valve used for?

A valve is a device used to control fluids, gases and liquids. It can open, close or regulate the flow of fluid to control the pressure, temperature and flow rate of the fluid. The valve usually consists of a valve body, a valve cover and a valve core. The valve is opened or closed by rotating, moving the valve core up and down or left and right. Valves are widely used in industry, construction, agriculture and household fields to control the flow direction and flow of fluids and protect the safe operation of equipment and pipeline systems.
