The different types of fixtures used in a bathtub include faucets, showerheads, drain plugs, and handles for controlling water temperature and flow.
A flow control valve is used to control and regulate the flow or pressure of fluids. A flow control valve may be used to regulate gas, steam, water and chemicals.
A water valve is used to regulate, direct, and control the flow of water. It can open, close, or partially obstruct passageways where water can travel and flow.
The fixtures on top of a gas well are typically called a wellhead or wellhead assembly. They are used to control and manage the flow of gas and other fluids from the well, as well as to provide a connection point for equipment such as pipes and valves.
....but in countries like The Netherlands which are partly below sea level, windmills are used to control the level of water.
Resistors are used to control current flow.
Flow Control
The lever in a tap is the handle that is used to control the flow of water. When the lever is moved, it either opens or closes the internal valve mechanism to allow water to flow or stop.
Flow control is used in data communications. Flow control is a process that manages the rate at which data is transmitted to ensure that it is properly received.
A water pressure regulator with gauge is used to control and monitor the water pressure in a plumbing system. It helps maintain optimal water pressure by regulating the flow of water to prevent pressure from becoming too high or too low. This ensures that the plumbing system functions properly and prevents damage to pipes and fixtures.
Control valves are typically used to control pressure, flow or the temperature of a liquid. They are used with plumbing in homes and hot water heaters. They are also used in vehicles. Control valves are used to control things like pressure, flow, temperature and liquid levels. There are many types of equipment that feature them, including manufacturing vats.
A hammer arrester valve in a plumbing system is used to prevent water hammer, which is a loud banging noise that occurs when water flow is suddenly stopped. The valve absorbs the shock caused by the sudden stoppage of water flow, protecting the pipes and fixtures in the plumbing system from damage.
